Abstract

Novel bis(acetylacetonato-O,O′)(biphenyldiolato-O,O′)titanium(IV) is synthesized and characterized by X-ray crystallography and other physical methods. The kinetics of substitution of bidentate 2,2′-biphenyldiolato for the two monodentate Cl^- ligands in Ti(CH₃COCHCOCH₃)₂Cl₂ proceeds via a 7-coordinated transition state according to an associative mechanism. The Ti(CH₃COCHCOCH₃)₂biphen complex exhibits high hydrolytic stability.
