Additions of allylic and benzylic zinc reagents to (η6-arene)Mn(CO)3 cations proceed in an anti fashion to give the C-6 allylic- and benzylic-substituted (η5-cyclohexadienyl)Mn(CO)3 neutral complexes, respectively. The reaction of less reactive primary organozinc reagents bearing an ester or a cyano group with the cations affords the α-alkylation products. Treatment of the organozinc reagent containing an acetoxy group with (η6-benzene)Mn(CO)3+ complex in THF results in alkylation of the cation at the C-2 position of THF.
