摘要：

Dehydrations of N-arylmaleamic acids in acetic anhydride with and without sodium acetate were studied, N-Arylmaleimides, N-arylmaleisoimides, maleic anhydride, and substituted acetanilides were detected in these reactions. Mechanisms to account for these products were discussed. The kinetics of the acetate-catalyzed rearrangement of N-arylmaleisoimides to N-arylmaleimides were investigated. This reaction was shown to be a major source of maleimides in the dehydration reactions. © 1969, American Chemical Society. All rights reserved.
