Abstract

Reaction of [Cp2TiCl2] with two equivalents of 2, 4-pentanedione in the presence of one equivalent of NEt3 in CH3CN at room temperature yielded oxo-bridged binuclear titanium complex [{Ti (acac) 2Cl}{TiCp2 (Cl)}(μ-O)], which was characterized crystallographically and spectroscopically. Reaction mixture of oxo-bridged binuclear titanium complex and 2nBuLi catalytically activate the mixture of phenylsilane and aldehyde to yield O-silation products ...
