Title:
FIXED LEWIS ACID CATALYST
Document Type and Number:
Japanese Patent JP3197836
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a fixed Lewis acid catalyst high in reaction rate and reaction yield, easy in recovery and reuse, having rare earth metal in an active center and produced by fixing on a polymer compound, and the producing method, a synthesis of an organic compound using the Lewis acid catalyst and a producing method an organic compound library.
SOLUTION: The fixed Lewis acid catalyst is produced by allowing the polymer compound to react with the Lewis acid catalyst having the rear earth element as the active center to fix the Lewis acid catalyst on the polymer compound. The Lewis acid catalyst is expressed preferably by a general formula, MA3. (wherein the formula, M represents the rare earth element. And a represents a group expressed by as general formula, CnF2n+1SO3 ((n)represents integers of 1-8) or a halogen atom).
