Article abstract of DOI:10.1021/ic50201a035

A number of soluble (chlorosilyl)phosphine complexes of rhodium(I) which are capable of being polymerized into poly(siloxyphosphine)-rhodium(I) species have been synthesized and characterized. They are L₂′Rh(CO)Cl, L′₃RhCl, L″₃RhCl, and L′₄Rh₂Cl₂ (L′ = Cl₃Si(CH₂)₂P(C₆H₅) ₂, L″ = Cl₃Si(CH₂)₈P(C₆H₅) ₂). Soluble siloxyphosphine-rhodium(I) complexes LRh(NBD)Cl, L₂Rh(CO)Cl, L₃RhCl, and L₄Rh₂Cl₂ (NBD = norbornadiene, L = [(CH₃)₃SiO]₂(CH₃)Si(CH ₂)₂P(C₆H₅)₂) have also been synthesized and characterized and their reactions with gaseous H₂, CO, and HCl as well as their catalytic behavior in hydrogenation reactions have been studied. These complexes were prepared to serve as study models for their polymeric counterparts.
