Chiral acyclic diaminocarbene complexes of palladium(II) immobilized on a polymeric support as promising catalysts of the Suzuki reaction

Abstract

Metal-promoted nucleophilic addition of primary amino group of a natural L-amino acid anchored on polystyrene support to coordinated isonitrile substrate has afforded preparation and simultaneous immobilization of chiral acyclic diaminocarbene complex of palladium(II). The obtained catalytic system is stable under conditions of the Suzuki reaction and demonstrates good catalytic activity in the reaction with a sterically hindered substrate.
