New Rhodium (II) Catalysts for Selective Carbene Transfer Reactions

Abstract
Rh2(PC)2(OCOR)2 complexes, (PC = orthometalated phosphines, OCOR = carboxylates), (1a-1j), with very polarizable ligands, such as aromatic rings directly joined to the rhodium atoms, have been prepared. Their utility for chemoselective intramolecular carbene transfer has been demonstrated in the catalyzed decomposition of 1-diazo-3-phenyl-5-hexen-2-one (2), 1-diazo-5-methyl-3-(2-propenyl)-2-hexanone (3) and 1-diazo-5-methyl-3-phenyl-2-hexanone (4).
