Reactions of cationic transition metal acetonitrile complexes [M(CH3CN)n]m+ with GaCp*: novel gallium complexes of iron, cobalt, copper and silver†‡
Abstract
The reactions of the cationic transition metal acetonitrile complexes [M(CH3CN)n]m+ (m = 2: M = Fe, Co and m = 1: M = Cu, Ag) with GaCp* were investigated. The reaction of [Fe(CH3CN)6][BArF]2 (BArF = [B{C6H3(CF3)2}4) with GaCp* leads to [Cp*Fe(GaCp*)3][BArF] (1) via a redox neutral Cp* transfer and [Ga2Cp*][BArF] as a by-product while the formation of [Cp*Co(GaCp*)3][BArF]2 (2) from [Co(CH3CN)6][BArF]2 is accompanied by
