Abstract

A number of stable isoimides have been prepared by acylation and sulfonylation of <i>O</i>-benzylbenzohydroxamic acid and <i>O</i>-butylbenzohydroxamic acid by anisoyl chloride, benzoyl chloride, phenoxyacetyl chloride, <i>p</i>-toluenesulfonyl chloride, benzenesulfonyl chloride and <i>p</i>-nitrobenzenesulfonyl chloride in the presence of pyridine. Spectral investigations indicate that the products have the mixed anhydride structure with (<i>Z</i>)-configuration. Corresponding (<i>E</i>)-isomers and isomeric N-acetylated products if formed, could not be isolated. An attempt has been made to study 1,3-rearrangement of the mixed anhydrides by thermal method.
