## Abstract Various propargylic and allenic aluminum reagents have been easily prepared by a direct insertion of aluminum into propargylic bromides in the presence of PbCl~2~ (1โ molโ%). These organoaluminum reagents react with carbonyl compounds to afford the corresponding allenic alcohols or homop
