A solid-phase-supported transition metal complex catalyst which is represented by the formula (I) (I) (wherein A represents a polystyrene/polyethylene glycol copolymer resin; Q represents lower alkyl, lower alkoxy, or a heterocycle optionally substituted by a halogen atom; L<1> and L<2> are the same or different and each represents halogeno, acetoxy, trifluoroacetoxy, trifluoromethanesulfonyl, tetrafluoroborate, or pi -allyl; and M represents copper, palladium, nickel, cobalt, rhodium, or platinum); and a solid-phase-supported transition metal catalyst which comprises a compound represented by the formula (II) (II) (wherein A and Q have the same meanings as defined above) and supported thereon a transition metal selected among copper, palladium, nickel, cobalt, rhodium, and platinum. These catalysts are usable in various reactions, can be used to conduct reactions in an aqueous system, have sufficient catalytic activity even in an oxygen atmosphere, and can be recovered and reused. |
