Synthesis and crystal structure of oxo-bridged binuclear titanium complex [{Ti(acac)2Cl}{TiCp2(Cl)}(μ-O)] and its catalytic reactions toward silation of aldehyde
摘要:
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)(2)Cl} {TiCP2(Cl)} (mu -O)], which was characterized crystallographically and spectroscopically. Reaction mixture of oxo-bridged binuclear titanium complex and 2 " BuLi catalytically activate the mixture of phenylsilane and aldehyde to yield O-silation products at room temperature.
