Resumen

The selective catalytic activity of various [Rh2(μ-Az)2(CO)2L2] complexes in the low pressure hydroformylation reaction has been examined. With Az = triazolate or benzotriazolate, the activity decreases in the sequence PPh3 > P(OMe)3 > P(OPh)3, and the dinuclear structure is presumably retained during the catalytic cycle. However, with Az = tetrazolate the inverse order of activity (P(OPh3)3 > P(OMe)3 > PPh3) is observed; this is probably due to cleavage of the bridging ligand during the reaction. Under the same conditions the mixed complex [(COD)Rh(μ-pyrazolate) 2Pt(dppe)]+ is completely inactive. © 1987.
