Elementary steps ester formation as chain termination

5 Elementary steps ester formation as chain termination 

These reductive eliminations occur for instance also in cross-coupling reactions where they are particularly effective when one of the partners of the reductive elimination has an sp2-hybridised carbon atom bonded to the metal. A theoretical analysis of the reductive elimination of propene from cis-(PH3)2Pd(CH3)(CH=CH2) shows that the best description for this reaction is a migration of the methyl group to the sp2-carbon of the vinyl unit [48],
