Patent ID: 8735522

Claim:
A gold-polymer nanostructure-immobilized Scandium catalyst, which is formed by (1) preparing, in liquid phase, a mixture comprising gold clusters having particle diameters of from 1 to 50 nm, a disulfide monomer, a sulfonic acid salt of a disulfide, and a Lewis acid metal compound represented by ScY 3 , wherein Y is a halogen atom, OAc, OCOCF 3 , ClO 4 , SbF 6 , PF 6 or OSO 2 CF 3 , and (2) polymerizing the mixture in the presence of a radical polymerization initiator, wherein the disulfide monomer is represented by the formula below: CH 2 ═CH—R 1 —S—S—R 1 —CH═CH 2 , wherein R 1 represents a divalent hydrocarbon, which may contain an ether bond, and wherein the sulfonic acid salt of the disulfide is represented by the formula below: MO 3 S—R 2 —S—S—R 2 —SO 3 M, wherein R 2 represents a divalent hydrocarbon, which may contain an ether bond, and M represents an alkali metal.
