Abstract

The direct synthesis of trifluoromethylindium reagents prepared from trifluoromethyl iodide by using just one equivalent each of indium, lithium chloride or sodium iodide, and ferrocene is reported. The weak In···F interaction is suitable to prepare stable but nucleophilic perfluoroalkyl reagents, which were successfully employed in the perfluoroalkylation of aldehydes. Notably, the nucleophilic trifluoromethylation of various aldehydes took place with trifluoromethyl iodide by utilizing just one equivalent each of indium, lithium chloride, and ferrocene.
