family of practical, liquid trifluoromethylation and pentafluoroethylation reagents is described. We show how halogen bonding can be used to obtain easily handled liquid reagentsfrom gaseous CF3I and CF3CF2I. The synthetic utility of the new reagents is exemplified by a novel direct arene trifluoromethylation reaction as well as adaptations of other perfluoroalkylation reactions.

A copper-mediated oxidative pentafluoroethylthiolation of arylboronicacids with TMSC2F5 and S8 was developed. This reaction provides a new access to various aryl pentafluoroethyl thioethers. The use of 2-fluoropyridine as the ligand and the ability to carry out the reaction at 70 °C are key features of this oxidative coupling reaction.
