Trifluotomethylcopper and pentafluoroethylcopper are prepared conveniently via the reaction of the solid complex Zn(CF3)Br center dot 2DMF with copper(I) bromide in N,N-dimethylformamide. The reactions of both copper species with 2,4-dinitrochlorobenzene, 4-iodonitrobenzene, 4-nitrobenzyl iodide, 4-bromobenzoic acid ethyl ester, 4-iodobenzoic acid ethyl ester, 2-iodopyridine and 2-iodopyrimidine have been studied. The structure of 2,4-dinitrotrifluoromethylbenzene has been elucidated. (C) 2009 Elsevier B.V. All rights reserved.
