First catalytic allyltitanation reactions

摘要

Catalytic allyltitanation reactions were accomplished from dienes and aldehydes with only 5% of titanocene complexes at the expense of employing stoichiometric amounts of PMHS.pi-Allyltitanium complexes can be readily prepared by hydro-titanation of conjugated dienes by [Cp_2TiH] generated in situ by the reaction of Cp_2TiCl_2 with Grignard reagent.
