Solid-supported transition metal complex catalystsneach of which is represented by the following formulan(I) :n nwherein A represents a polystyrene-polyethylene glycolncopolymer resin, Q represents a heterocycle which may bensubstituted by one or more lower alkyl groups, lowernalkoxy groups or halogen atoms, L 1 and L 2 may be the samenor different and each represents a halogen atom or annacetoxy, trifluoroacetoxy, trifluoromethanesulfonyl,ntetrafluoroborate or π-allyl group, and M representsncopper, palladium, nickel, cobalt, rhodium or platinum;nand S-solid-supported transition metal catalysts each ofnwhich comprises a compound, which is represented by thenfollowing formula (II):n nwherein A and Q have the same meanings as defined above,nand a transition metal selected from copper, palladium,nnickel, cobalt, rhodium or platinum and supported on saidncompound. n These catalysts are usable for a wide variety ofnreactions, permit conducting the reactions in water nsystems, exhibit sufficient catalytic functions even innoxygen atmosphere, and allow recovery and reuse. |
