The Suzuki-Miyaura arylation of aryl trifluoromethyl sulfones via C-SO2 bond cleavage has been developed by means of cooperative palladium/rhodium catalysis. A series of aryl trifluoromethyl sulfones and arylboronic acid neopentylglycol esters are converted to the corresponding biaryls. Mechanistic investigations suggest that (1) the rhodium catalyst mediates the transfer of the aryl ring from arylboronate to palladium, resulting in the acceleration of the transmetalation step, and (2) the C-C bond-forming reductive elimination step is the turnover-limiting step.

The action of silver fluoride on C3F7Fe(CO)4I in the presence of aromatic substrates (benzene, toluene, anisole, furan) at 20 deg C led to the formation of perfluoroalkylation products.On the basis of the isomeric composition of the obtained perfluoropropyl derivatives of toluene and anisole it was concluded that the process was cationic in nature.Perfluoropropyltoluenes were obtained when C3F7Fe(CO)4OCOCF3 or (C3F7)2Fe(CO)4 were heated in toluene.The cationic complex +BF4- reacts with dimethylaniline and with sodium p-toluenethiolate to form p-perfluoropropyldimethylaniline and p-tolyl perfluoropropyl sulfide.

It has been shown that under conditions of phase-transfer catalysis under UV-irradiation perfluoroalkyl iodides react with aliphatic and aromatic thiols in the water-organic solvent media to form alkyl or aryl perfluoroalkyl sulfides in 60-80 percent yields.
