Resin-Platinum Complex and Resin-Supported Platinum Cluster Catalyst

A method for producing a resin-supported platinum cluster complex comprising the steps of:

• (a) forming a platinum complex represented by the general formula (chemical formula 2)
• R1NR22—PtX3-nR3n
• , wherein R1 is a carrier containing a hydrophilic polymer chain, R2, may be identical or different, is a hydrogen atom, an alkyl group, an aryl group, and, however, NR22 may form a pyridine ring, an acridine ring or a quinoline ring, X is a halogen atom, R6COO—, SO4—, CN—, NO3— or SCN—, wherein R6 is an alkyl group or an aryl group, R3 is an unsaturated organic ligand, n is an integer from 0 to 4,
• from a nitrogen-containing compound represented by the general formula (chemical formula 1)
• R1NR22
• , wherein R1 and R2 are the same as defined above, and
• a platinum compound represented by the general formula
• M(PtX3-nR3n)m
• , wherein M is an alkali metal, an alkaline earth metal or a quaternary ammonium ion represented by N+R54, wherein R5, may be identical or different, is a hydrogen atom, an alkyl group or an aryl group, m is an integer indicating the electrical charge number of M, and X, R3 and n are the same as defined above, and
• (b) allowing the platinum complex to react with a reducing agent.
