Reaction of the dimers [RuCl2(η6-arene)]2 (arene = mesitylene a, p-cymene b, C6H6 c) with salicyloxazolines in the presence of NaOMe gives the corresponding [RuCl(R,R’-saloxaz)(arene)] (R = R’ = Me 1; R = H, R’ = Me2CH 2, Me3C 3, PhCH2 4, Ph 5), which were fully characterized. [RuL(iPr-saloxaz)(mes)]Y (L = py 6, 2-Mepy 7, 4-Mepy 8, PPh3 9; Y- = SbF6 or BPh4) were prepared by treating the chloride 2a with ligand L and NaY (Y- = SbF6 or BPh4) in MeOH at reflux. Halide complexes [RuX(iPr-saloxaz)(mes)] (X = Br, 10; X = iodo, 11) were synthesized by treating 2a with AgSbF6 then with 1.2 equiv KBr or NaI, whereas the Me complex [RuMe(iPr-saloxaz)(mes)] 12 was synthesized from 2a by reaction with MeLi. Five complexes, [RuCl(iPr-saloxaz)(mes)] 2a, [RuCl(tBu-saloxaz)(p-cymene)] 3b, [RuCl(Ph-saloxaz)(mes)] 5a, [Ru(4-Mepy)(iPr-saloxaz)(mes)][SbF6] 7, and [Ru(PPh3)(iPr-saloxaz)(mes)][SbF6] 9, were characterized by x-ray crystallog.

Cp*rhodium complexes with salicyloxazolines: Diastereoselective synthesis, configurational stability and use as asymmetric catalysts for a Diels-Alder reaction was written by Davenport, Adam J.; Davies, David L.; Fawcett, John; Russell, David R..

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. Three complexes, [RhCl(Me2-saloxaz)Cp*] (1), [RhCl{(S)-iPr-saloxaz}Cp*] (2), and [Rh(OH2)(Me2-saloxaz)Cp*][SbF6] (6) were characterized by x-ray crystallog. Some of the complexes, after treatment with AgSbF6, were tested as enantioselective catalysts for the Diels-Alder reaction of methacrolein with cyclopentadiene, but gave much poorer results than the corresponding arene ruthenium complexes.

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).

Oxazolidine-based compounds have started to attract attention also in the medicinal and materials chemistry fields. Oxazolidines are cyclic condensation products of β-amino alcohols and aldehydes or ketone, and they undergo a facile and complete hydrolysis in aqueous solution. Alterations in carbonyl moiety control the rate of formation of a given β-amino alcohol. Oxazolidines are weaker bases (pKa 6–7) than parent β-amino alcohols and found to be more lipophilic than the parent compound at physiological pH.Related Products of 163165-91-1

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 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.
