Mechanism of reactions of acyl isocyanates with azomethines

Abstract

A study of the isomerization of the adducts, and the isolation of the free bipolar ion from the reaction of trichloroacetyl isocyanate with p-dimethylaminobenzalaniline, disclosed that the reaction of acyl isocyanates with azomethines belongs to the type of 1,4-dipolar cycloaddition. © 1977 Plenum Publishing Corporation.
