Title GOLD POLYMER NANO-STRUCTURE-SUPPORTED SCANDIUM CATALYST AND USE OF THE SAME
Abstract Disclosed is a scandium catalyst that can be used with water and a water-soluble organic solvent, and does not leak scandium. In a liquid phase, this is a gold polymer nano-structure-supported scandium catalyst formed by mixing Lewis acid metallic compounds represented by gold clusters with particle diameters on the order of 1 - 50 nm, disulfide monomer, disulfide sulfonate, and ScY3 (in the formula, Y represents OSO2CF3) and polymerizing in the presence of an initiator of radical polymerization, the disulfide monomer represented by the following formula CH2 = CH - R1 - S - S - R1 - CH = CH2 (in the formula, R1 represents a bivalent hydrocarbon radical that can include an ether bond), and the disulfide sulfonate represented by the following formula MO3S - R2 - S - S - R2 - SO3M (in the formula, R2 represents a bivalent hydrocarbon radical that can include an ether bond; M represents alkali metal). The catalyst is used for an aldol reaction in water or a water-soluble organic solvent, a cyano reaction, an allyl reaction, a Michael reaction, a Mannich reaction, a Diels-Alder reaction or a Friedel-Crafts reaction.
