Catalytic Reactions Using Polymer-Bound Versus Homogeneous Complexes of Ni, Rh, and Ru.
Abstract
A series of styrene-divinylbenzene resins were diphenylphosphinated and then complexed with the homogeneous catalysts (PPh3)2Ni(CO)2, (PPh3)3RhCl, (PPh3)3RhH(CO), and (PPh3)2RhCl2(CO)2. Reactions catalyzed by the polymer-anchored catalysts were compared with the same reactions carried out with the corresponging homogeneous catalyst. Butadiene cyclooligomerizations were effected. The rates of hydroformylation as a function of the polymer-bound -PPh2/Rh ratio, crosslink density, resin particle size, and diffusion effects are discussed. The effect of catalyst anchoring on hydrogenation rates was discussed for some cycloalkenes. A comparison of homogeneous versus anchored catalysts in terms of rates, diffusion, internal polymer mobility and product selectivity is made where possible.
