Oxazoline Early Transition Metal Complexes: Functionalizable Achiral Titanium(IV), Titanium(III), Zirconium(IV), Vanadium(III), and Chiral Zirconium(IV) Bis(oxazoline) Complexes was written by Cozzi, Pier Giorgio; Floriani, Carlo; Chiesi-Villa, Angiola; Rizzoli, Corrado. And the article was included in Inorganic Chemistry on May 24,1995.Formula: C11H13NO2 The following contents are mentioned in the article:
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. Crystallog. details are as follows: 11 is monoclinic, space group I2/a, with a 16.443(2), b 8.365(1), c 17.945(2) Å, β 106.93(1)°, Z = 4, and R = 0.034; 12 is orthorhombic, space group Pca21, with a 15.669(2), b 17.750(3), c 18.971(3) Å, Z = 8, and R = 0.050; 14 is monoclinic, space group P21/n, with a 9.391(4), b 28.618(6), c 12.077(4) Å, β 105.79(2)°, Z = 4, and R = 0.052; 16 is monoclinic, space group P21, with a 10.161(2), b 14.151(3), c 12.361(2) Å, β 93.76(2)°, Z = 2, and R = 0.033. This study involved multiple reactions and reactants, such as 2-(4,4-Dimethyl-4,5-dihydrooxazol-2-yl)phenol (cas: 163165-91-1Formula: C11H13NO2).
2-(4,4-Dimethyl-4,5-dihydrooxazol-2-yl)phenol (cas: 163165-91-1) belongs to oxazolidine derivatives.Oxazolidines are readily available also from propargyl amines. 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.Formula: C11H13NO2
