N2 - Several μ-thiolato-μ-chlorodicarbonylbis(tri-t-butylphosphine)dirhodium complexes were anchored (a) to diphenylphosphinated crosslinked polystyrene by phosphine ligand exchange, (b) to chloromethylated polystyrene resin by substitution of the benzylic halogen via the μ-thiolato group, and (c) to silica and alumina via a sulfur-attached -CH2CH2SiO3bridge. The catalytic activity of the various immobilized dirhodium complexes in allylic isomerization, hydrogenation and hydroformylation processes were investigated. Some mechanistic features of these catalyses are discussed.
