Abstract

A comprehensive FT-Raman and -IR vibrational spectroscopic study of [C₆H₅)₃P]₃ M Cl species, where M is Rh, Ru, Co and Cu, has been made. These species are of interest since they are used as hydrogenation catalysts for alkenes and polydienes. Comparison with the free triphenylphosphine ligand has facilitated the assignment of (nu) (MCl) and (nu) (MP) vibrational modes, from which the relative strengths of ligand coordination can be inferred. From these studies it has been possible to identify and monitor the extent of incorporation of organophosphine metal catalysts into partially hydrogenated polydienes of commercial application.
