Recently, N,N-trans Re(O)(LN-O)2X (LN-O = monoanionic N-O chelates; X = Cl or Br prior to being replaced by solvents or alkoxides) complexes are superior to the corresponding N,N-cis isomers in the catalytic reduction of perchlorate via oxygen atom transfer. However, reported methods for Re(O)(LN-O)2X synthesis often yield only the N,N-cis complex or a mixture of trans and cis isomers. This study reports a geometry-inspired ligand design rationale that selectively yields N,N-trans Re(O)(LN-O)2Cl complexes. Anal. of the crystal structures revealed that the dihedral angles (DAs) between the two LN-O ligands of N,N-cis Re(O)(LN-O)2Cl complexes are <90°, whereas the DAs in most N,N-trans complexes are >90°. Variably sized alkyl groups (-Me, -CH2Ph, and -CH2Cy) were then introduced to the 2-(2′-hydroxyphenyl)-2-oxazoline (Hhoz) ligand to increase steric hindrance in the N,N-cis structure, and substituents as small as -Me completely eliminate the formation of N,N-cis isomers. The generality of the relation between N,N-trans/cis isomerism and DAs is further established from a literature survey of 56 crystal structures of Re(O)(LN-O)2X, Re(O)(LO-N-N-O)X, and Tc(O)(LN-O)2X congeners. D. functional theory calculations support the general strategy of introducing ligand steric hindrance to favor synthesis of N,N-trans Re(O)(LN-O)2X and Tc(O)(LN-O)2X complexes. This study demonstrates the promise of applying rational ligand design for isomeric control of metal complex structures, providing a path forward for innovations in a number of catalytic, environmental, and biomedical applications.

Five Ru complexes [Ru(p-cymene)LCl] containing phenolate-oxazoline ligands [LH = 2-(4,5-dihydrooxazol-2-yl)phenol (1), 2-(4-methyl-4,5-dihydrooxazol-2-yl)phenol (2); L = 2-(4-ethyl-4,5-dihydrooxazol-2-yl)phenol (3), 2-(4-phenyl-4,5-dihydrooxazol-2-yl)phenol (4), 2-(4,4-dimethyl-4,5-dihydrooxazol-2-yl)phenol (5)] were synthesized and characterized. The solid-state structures of all Ru complexes were determined by single-crystal x-ray diffraction. The catalytic activities of these complexes in the transfer hydrogenation reaction of nitroarenes to anilines were studied. Aniline and their derivatives were obtained in good to excellent yields with iso-PrOH as the hydride source. The present protocol provides an environmentally benign synthetic method for the reduction of nitroarenes to anilines without employing harsh reaction conditions. Theor. studies employing d. functional theory were carried with the aim to propose a feasible reaction mechanism and to draw insights into the reactivity of the half-sandwich Ru catalyst.

The syntheses and characterizations of oxidorhenium(V) complexes trans-dichlorido [ReOCl2(PPh3)(L1a)] (trans-2a), cis-dichlorido [ReOCl2(PPh3)(L1b)] (cis-2b) and ethoxido-complex [ReO(OEt)(L1b)2] (4b), ligated with the dimethyloxazoline-phenol ligands HL1a and HL1b are described. The bidentate ligand HL1a (2-(4,4-dimethyl-4,5-dihydro-1,3-oxazol-2-yl)phenol) is unsubstituted on the phenol ring; ligand HL1b (2-(4,4-dimethyl-4,5-dihydro-1,3-oxazol-2-yl)-4-nitrophenol) contains a nitro group in para-position to the hydroxy group. In the reaction of precursor complex [ReOCl3(PPh3)2] and HL1a the two stereoisomers cis/trans-2a, with respect to chlorido ligands, are formed. The solid state structures of both isomers cis- and trans-2a were determined by single crystal x-ray diffraction anal. In contrast, with ligand HL1b, only the cis-isomer cis-2b was obtained. Ethoxido-complex 4b is exclusively obtained when precursor [ReOCl3(OPPh3)(SMe2)] is reacted with 2 equiv of HL1b in ethanol in the presence of the base 2,6-dimethylpyridine (lutidine). If no lutidine was added, chlorido-complex [ReOCl(L1b)2] (3b) was obtained. Complexes [ReOCl2(PPh3)(L1a)] (cis/trans-2a), [ReOCl2(PPh3)(L1b)] (cis-2b), [ReO(OMe)(L1a)2] (4a) and [ReO(OEt)(L1b)2] (4b) were tested as homogeneous catalysts in the benchmark reaction of cyclooctene epoxidation The influence of isomerism and effects of ligand substitutions on catalytic activity was studied. Based on the time-conversion plots cis/trans-isomerism does not influence catalytic activity, but electron-withdrawing substituents, as in cis-2b, 3b and 4b, show a beneficial effect. This study involved multiple reactions and reactants, such as 2-(4,4-Dimethyl-4,5-dihydrooxazol-2-yl)phenol (cas: 163165-91-1Reference of 163165-91-1).

The syntheses of oxidorhenium(V) complexes [ReOCl(L1a-c)2] (3a-c), equipped with the bidentate, mono-anionic phenol-dimethyloxazoline ligands HL1a-c are described. Ligands HL1b-c contain functional groups on the phenol ring, compared to parent ligand 2-(4,4-dimethyl-4,5-dihydro-1,3-oxazol-2-yl)-phenol H1a; namely a methoxy group ortho to the hydroxyl position (2-(4,4-dimethyl-4,5-dihydro-1,3-oxazol-2-yl)-6-methoxyphenol, H1b), or a nitro group para to the hydroxyl position (2-(4,4-dimethyl-4,5-dihydro-1,3-oxazol-2-yl)-4-nitrophenol, H1c). Furthermore, oxidorhenate(V) complexes (NBu4)[ReOCl3(L1a-b)] (2a-b) were synthesized for solid state structural comparisons to 3a-b. All novel complexes are fully characterized including NMR, IR and UV-Vis spectroscopy, MS spectrometry, X-ray crystallog., elemental anal. as well as cyclic voltammetry. The influence of functional groups (R = -H, -OMe and -NO2) on the catalytic activity of 3a-c was investigated in two benchmark catalytic reactions, namely cyclooctene epoxidation and perchlorate reduction In addition, the previously described oxidorhenium(V) complex [ReOCl(oz)2] (4), employing the phenol-oxazoline ligand 2-(4,5-dihydro-2-oxazolyl)phenol Hoz, was included in these catalysis studies. Complex 4 is a rare case in oxidorhenium(V) chem. where two stereoisomers could be separated and fully characterized. With respect to the position of the oxazoline nitrogen atoms on the rhenium atom, these two stereoisomers are referred to as N,N-cis and N,N-trans isomer.

Homoleptic tris-chelate complexes ML3 (M = Al or rare earth; L = chiral or achiral oxazolyl-phenolate or -naphtholate) is reported. In all cases, complexes crystallize as mer-isomers and complete diastereoselectivity is observed on crystallization of the complexes: ML3 crystallize with Λ-helicity at the metal where L = (S)-oxazolylphenolate. Complexes were characterized in solution by NMR spectroscopy, demonstrating rapid ligand exchange at ambient temperature for rare earth complexes, and slow exchange on the NMR timescale for complexes of Al; in all cases the mer-isomer is observed exclusively.

Large-scale syntheses of the (hydroxyphenyl)oxazoline ligands [I; R = R’ = Me, R” = H (L1); R = CH2Ph, R’ = R” = H (L2); R = CHMe2, R’ = R” = H (L3); R = Me, R’ = H, R” = Ph (L4); R = Ph, R’ = R” = H (L5)] are reported. The conversion of L1-L5 into the corresponding sodium salts was employed for metal complexation. The reaction of L1 with TiCl4·2THF, TiCl3·3THF, ZrCl4·2THF, and VCl3·3THF in a 1:2 metal:ligand ratio afforded the corresponding hexacoordinate functionalizable metal complexes: cis-[Cl2Ti(L1)2], 11; cis-[(THF)ClTi(L1)2], 12; cis-[Cl2Zr(L1)2], 13; trans-[(THF)ClV(L1)2], 14. The structures of 11, 12, and 14 were clarified by x-ray anal. The reaction of the L3 and L4 sodium salts with ZrCl4·2THF in a 1:2 metal:ligand ratio led to the corresponding chiral functionalizable metal complexes, whose structures were clarified by x-ray anal.: cis-[Cl2Zr(L3)2], 15; cis-[Cl2Zr(L4)2], 16. A common significant feature discovered from these studies is the existence of intramol. hydrogen bonding, which is probably responsible for the high conformational rigidity of the oxazoline ligand.

The previously published oxidorhenium(V) complex [ReOCl(L1)2] (2), equipped with the bidentate phenol-dimethyloxazoline ligand HL1 (2-(4,4-dimethyl-4,5-dihydro-1,3-oxazol-2-yl)-phenol), shows catalytic activity for the reduction of nitrate to nitrite under mild, ambient and aqueous conditions. The reaction operates under an oxygen atom transfer (OAT) mechanism, using di-Me sulfide SMe2 (DMS) as oxygen acceptor. Experiments with catalytic amounts of 2 and labeled 15NO-3 proved the full reduction of 15NO-3 to 15NO-2 by 15N NMR spectroscopy. For the second reduction step of nitrite NO-2, we have evidence for a single electron reduction to yield paramagnetic NO, as from one nitrate reduction experiment the paramagnetic cis-dioxidorhenium(VI) complex [Re(O)2(L1)2] (3) could be isolated and characterized by single-crystal X-ray diffraction anal. Such a single electron reduction of nitrite NO-2 would yield NO and complex 3 as the oxidation product. In a stoichiometric experiment of 2, 15NO-3 and DMS, nitrous oxide 15N2O could be detected as the only 15N containing product by 15N NMR spectroscopy, proving that further reduction beyond NO is possible with pre-catalyst 2. The rhenium species responsible for the reduction to N2O is currently unknown. Most likely, N2O is formed via an intermediate rhenium nitrosyl complex. Exptl. data was gathered by 1H and 15N NMR, IR- and UV-Vis spectroscopy, HR-ESI mass spectrometry, X-ray crystallog., and supported by theor. computations (DFT).

Reaction of [RhCl2Cp*]2 (Cp* = η-C5Me5) with appropriate salicyloxazolines in the presence of NaOMe gave 72-83% [RhCl(R,R’-saloxaz)Cp*] [R = R’ = Me (1); R = H, R’ = Me2CH (2), PhCH2 (3), Ph (4)] which were fully characterized; complexes 2-4 contain an enantiopure (S)-saloxaz ligand. The diastereoselectivity of complexation depends on the substituents and the absolute configuration at the metal center is unstable in solution Thus, salicyloxazoline ligands coordinate diastereoselectively to the Cp*RhCl fragment with the oxazoline substituent oriented towards the chloride except in the case of the Ph-substituted complex. Treatment of 2 with 4-methylpyridine and NaSbF6 in MeOH at reflux gave [Rh(4-Mepy){(S)-iPr-saloxaz}Cp*][SbF6] (5) while [Rh(OH2)(Me2-saloxaz)Cp*][SbF6] (6) was prepared by reaction of 1 with AgSbF6.
