A number of stable isoimides have been prepared by acylation and sulfonylation of O-benzylbenzohydroxamic acid and O-butylbenzohydroxamic acid by anisoyl chloride, benzoyl chloride phenoxyacetyl chloride, p-toluenesulfonyl chloride, benzenesulfonyl chloride and p-nitrobenzenesulfonyl chloride in the presence of pyridine.Spectral investigations indicate that the products have the mixed anhydride structure with (Z)-configuration.Corresponding (E)-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.
