Abstract Perfluoraliphatic mono-and di-Grignard reagents (R f MgX, XMgR′ f MgX) have been conveniently synthesized in excellent yields (90–100%) through metalhalogen exchange reactions. The degree of exchange has been found to be subject to a number of experimental parameters, eg the nature of the solvent (tetrahydrofuran vis-à-vis diethyl ether), the type of halide displaced, the organomagnesium exchange reagent and the ...
