Abstract:

Styrene-divinylbenzene resins have been functionalized with phosphine ligands and these phosphinated resins have been used to immobilize RhI, IrI, and PdO catalysts. The selectivity of RhI-catalyzed hydroformylations and the optical yields in styrene hydroformylations have been examined as a function of ligand loading and PRh ratios. The rates of IrI-catalyzed hydrogenations of 1,5-cyclooctadienes and PdO-catalyzed butadiene dimerization-methoxylations were studied. In all cases the resin-catalyzed reactions were compared to their homogeneously catalyzed analogs. All the results appear to be explained in terms of the influence of the resin matrix on metal-ligand equilibria which play important roles in the reaction mechanisms. Author
