Trans-cis isomerization of dimethylbis(DIETHYLPHENYLPHOSPHINE (cas 1605-53-4))palladium(II) catalyzed by methylmagnesium compounds

Add time:07/18/2019    Source:sciencedirect.com

Dimethylbis(diethylphenylphosphine)palladium(II) complex was found to undergo a facile trans-cis isomerization 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 methylpalladium and methylmagnesium compounds involving a partial dissociation of phosphine ligand.
