Abstract
The reactions of Cd(C2F5)(2) . D and Zn(C2F5)(2) . D (D = 2 CH3CN, 2 DMF), respectively, with copper(I) halides in the presence of halides quantitativ ely yield the CUC2F5 compounds CuC2F5 . D and [CU(C2F5)(2)](-) The CUC2F5 c omplexes are identified by NMR spectroscopy, while [CU(C2F5)(2)](-) is isol ated as PNP salt (PNP = (C6H5)(3)PNP(C6H5)(3)(+)) Both compounds are excell ent C2F5 group transfer reagents, even at low temperature. Oxidation of [Cu (C2F5)(2)](-) with [(C2H5)(2)NC(S)S](2) yields the crystalline Cu(III) comp ound (C2F5)(2)CuSC(S)N(C2H5)(2) (monoclinic, C2/c).
