Dimethylbis(diethylphenylphosphine)palladium(II) complex was found to undergo a facile trans-cis isomerisation reaction in tetrahydrofuran containing methylmagnesium compounds such as Me2Mg and MeMgBr.Kinetic and isotopic studies on the isomerization process suggest the occurrence of methylmagnesium-catalyzed isomerization through an intermolecular methyl exchange process between methyl-palladium and methylmagnesium compounds involving a partial dissociation of phosphine ligand.
