Abstract
The present invention is draw to microwave heating of a transition metal-catalysed organic reaction, in which a catalyst complex between a transition metal and an auxiliary ligand or ligands, the ligand being asymmetric or symmetric, monodentate or bidentate, results in highly chemoselective, regioselective, and stereoselective allylic substitution reactions. Molybdenum or palladium complexes form suitable catalytic systems with a plethora of ligands in a variety of solvents for such microwave facilitated nucleophilic substitution reactions.
