The structural chemistry of titanium alkoxide derivatives with OH-substituted bidentate ligands

The organically modified titanium alkoxides Ti2(Oi-Pr)4(OOCCMe2O)2(i-PrOH)2 and Ti4(Oi-Pr)4(SA)6 were obtained from the reaction of Ti(Oi-Pr)4 with 2-hydroxy-isobutyric acid and salicyladoxime (SA-H2), respectively. Reaction of 1,3-dibenzoyl acetone (DBA-H) did not result in a substituted titanium alkoxide derivative, but instead in the oxo cluster Ti4O2(Oi-Pr)8(DBA)2 after allowing moisture to diffuse into the reaction mixture. The three titanium compounds show common structural features which are different to derivatives void of ligand OH groups. The latter play a decisive role in coordinating the ligands to the titanium centers. Graphic abstract

Synthesis and characterization of heteroleptic titanium MOCVD precursors for TiO2 thin films

Heteroleptic titanium alkoxides with three different ligands, i.e., [Ti(OiPr)(X)(Y)] (X = tridentate, Y = bidentate ligands), were synthesized to find efficient metal organic chemical vapor deposition (MOCVD) precursors for TiO2 thin films.

Highly catalytically active micro/meso-porous Ti-MCM-36 prepared by a grafting method

The effect of titanium alkoxides as grafting agents and various solvents in the preparation of Ti(iv)-incorporated micro/meso-porous MCM-36 (Ti-MCM-36) of highly catalytic activities and reusability was examined.
