The solid Lewis acid catalyst, production method of the deirusuaruda addition product which uses that

摘要

P 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 and using an applicable equal catalytic amount. PSOLUTION: The solid Lewis acid catalyst (MAO-NTfSB2/SB) is a chemical compound prepared through a chemical reaction shown by Formula. This chemical compound is composed of a sulfonimide-modified polyaluminoxane in whichSP13/SPC-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.
