Popis: Abstract 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
