transformations of phosphaalkene P–W(CO)5 complexes under H2 pressure in the presence of rhodium catalysts have been studied. In the presence of the cationic complex Rh(diphos)+ isomerization of phosphaalkene into secondary vinylphosphine complexes is greatly favoured. On the other hand, in the presence of the covalent Rh(diphos)Cl complexhydrogenation of the P=C double bond is greatly predominant. Experiments
