The present invention relates to a polymer-supported rhodium (II) catalyst and its application, which includes addition reaction to carbon-carbon multiple bond in ±-diazocarbonyl compounds, insertion reaction to C-H and X-H (X=N, O, S, Se, Si and the like) bonds, or rearrangement and additional cyclization reaction thereof. A novel insoluble polymer-supported rhodium (II) complex was prepared through a ligand exchange reaction between an insoluble polymer and a rhodium (II) carboxylato complex, wherein the insoluble polymer was prepared by a copolymerization reaction of (i) a styrene derivative with substituted carboxylic acid, (ii) a stylene, and (iii) a linear alkane with both ends substituted by vinylbenzyloxy groups, Namely, a polymer-supported metal complex catalyst having the following chemical formula 1:
wherein M 1 and M 2 are rhodium, and the like; and X is an oxygen atom, etc; and R 4 is an alkyl group, and the like; and k is 1 to 15%, m is 1 to 5% relative to k+1+m, and 1 is the remainder; and n is 4 and others; and R 1 is alkyl-2-(4'-alkyloxy phthalimido methyl), etc, R 2 is phenyl, etc; R 3 is 4, 4' -(1, 3-propyrene-1, 3-dioxymethyl) phenyl, etc.
