Identification and properties of bimetallic intermediates in the hydrolysis of titanium chloro carboxylate species. Crystal structure of Ti2(µ-O)(µ-O2CPh)2Cl4·2L (L = EtOAc or tetrahydrofuran)

Abstract

Partial hydrolysis of the titanium chlorocarboxylate derivatives TiCl_x(O₂CR)_4–x(R = Me, Ph, x= 3; R = Me, x= 2) in ethyl acetate or tetrahydrofuran (THF) solution yields the stable bimetallic compounds Ti₂(µ-O)(µ-O₂CR)₂Cl₄·2L (L = EtOAc, THF); X-ray data confirm the presence of bridging oxygen and carboxylate groups, and further reactions of the chlorocarboxylate compounds are discussed.
