Double C-H Activation. Dimerization of Esters Catalyzed by RhCl(CO)(PMe3)2 under Irradiation

Article abstract of DOI:10.1246/cl.1988.683

Dehydrogenation of methyl propionate yielded methyl 4-propionyloxybutyrate (head-to-tail dimer) by photocatalysis in the presence of RhCl(CO)PMe3)2 at room temperature.Methyl acrylate is presumed to be an intermediate.
