Reaction of ketones with the organotitanium oxide [{TiCp*(µ-O)}3(µ3-CMe)] via the hydride–vinylidene [{TiCp*(µ-O)}3(µ-CCH2)(H)] intermediate‡

Abstract

Thermal and/or photochemical treatment of [{TiCp*(µ-O)}₃(µ₃-CMe)] 1 (Cp* η⁵-C₅Me₅) with organic ketones affords the new oxo derivatives [{TiCp*(µ-O)}₃(µ-CCH₂)(OCHRR′)] (R = R′ = Me 2, Ph 3; R = Ph, R′ = Me 4, Et 5); these reactions take place by insertion of the ketones CO group into the Ti–H bond of the in situ formed [{TiCp*(µ-O)}₃(µ-CCH₂)(H)] intermediate.
