Polystyrene-supported rhodium(I)-1,10-phenanthroline complex as catalyst for hydrogenation

Abstract

Rhodium(I)-1,10-phenanthroline complex anchored to polystyrene catalyzes the hydrogenation of a variety of substrates. The rate is first order with respect to catalyst. The order with respect to substrate and hydrogen follows a first order rate law below the saturation limit of the catalyst and 1 atmosphere pressure of hydrogen, respectively. The following rate law is proposed: $$Rate \propto [Catalyst][{\rm H}_2 ]\frac{{[olefin]}}{{1 + [olefin]}}$$
