Four new well-defined CuI complexes bearing a C2F5 ligand have been prepared and fully characterized: [(Ph3P)2CuC2F5] (2), [(bpy)CuC2F5] (3), [(Ph3P)Cu(phen)C2F5] (4), and [(IPr)CuC2F5] (5). X-ray structures of all four have been determined, showing that the C2F5-ligated Cu atom can be di- (5), tri- (2 and 3), and tetracoordinate (4). The mixed phen-PPh3 complex 4 is a highly efficient fluoroalkylating agent for a broad variety of acid chlorides. This high-yielding transformation represents the first general method for the synthesis of RCOC2F5 from the corresponding RCOCl. Four well-defined CuC2F5 complexes have been prepared and fully characterized, with [(phen)Cu(PPh3)C2F5] (phen=1,10-phenanthroline) proving to be a remarkably efficient fluoroalkylating agent for a broad variety of acid chlorides (see scheme). The procedure represents the first general method for the one-step conversion of RCOCl into valuable pentafluoroethyl ketones.

Perfluorinated benzocycloalkenes (benzocyclobutene, indan, tetralin), alkylbenzocycloalkenes and alkylbenzenes react with CF3COOH/SbF5 at 20-50 °C giving the corresponding carbonyl derivatives.
