Abstract

A novel type of migration of an alkyl group in the formation of indene derivatives from titanacyclopentadienes was found. When titanacyclopentadienes with four alkyl groups were heated at 50 degrees C in THF for 24 h under nitrogen, titanium dihydroindene complexes were formed. Oxidation of the dihydroindene complexes with oxygen or alkyl halides afforded indene derivatives with unusual migration of one alkyl group at the diene moiety to the five-membered ring of the indene derivatives.
