SOLID LEWIS ACID CATALYST AND MANUFACTURING METHOD OF DIELS-ALDER ADDUCT USING THIS CATALYST

摘要

PROBLEM TO BE SOLVED: To provide a Lewis acid catalyst which is highly economical in that it can promote Diels-Alder reaction with high yield to monodentate and didentate dienophile compounds, using an applicable equal catalytic amount.

SOLUTION: The solid Lewis acid catalyst (MAO-NTf2) is a chemical compound prepared through a chemical reaction shown by Formula. This chemical compound is composed of a sulfonimide-modified polyaluminoxane in which13C-NMR of the carbonyl group is made to show a low magnetic field shift and its peak is present between 211.8 to 212.8 ppm when the chemical compound is brought into contact with cyclohexanone.
