Abstract:
Palladium
complexes of 2-pyridyldiphenylphosphine anchored on polystyrene,
polymethylmethacrylate and styrene–methylmethacrylate copolymer form
highly active heterogeneous catalysts for the alkoxycarbonylation of
terminal alkynes with activities approaching those obtained under
homogeneous conditions.
