摘要：

Reactions of [Cp*Fe-2] with the Lewis acid [Zn(C6F5)(2)] in the presence of [(PhC(S)S)(2)], 9,10-phenanthrenedione or 4,5-pyrenedione yield the salt [Cp*Fe-2][(PhC(S)S)Zn(C6F5)(2)] 1, [Cp*Fe-2][((C14H8O2)Zn(C6F5)(2))center dot] 4, and [Cp*Fe-2][((C16H8O2)Zn(C6F5)(2))center dot] 5, respectively. The latter two species represent the first examples of isolable zinc-containing radical anions. While [(PhC(S)S)(2)] binds weakly to [Zn(C6F5)(2)], the diones afford the isolable adducts [(C14H8O2)Zn(C6F5)(2)] 2 and [(C16H8O2)Zn(C6F5)(2)] 3. Cyclic voltammetry and computational studies support the view that 4 and 5 are formed via single electron transfer (SET) to the donor-acceptor adducts, 2 and 3, respectively. Subsequent treatment of 4 and 5 with [NC5H4NMe2] affords [Zn(C6F5)(2)(NC5H4NMe2)(2)] with liberation of the dione, and regeneration of [Cp*Fe-2].
