Abstract: Several stable isoimides have been prepared by acylation of O-benzyl-4-nitro-, O-(1-propyl)-, O-(1-propyl)-4-nitro-, O-benzyl-4-chloro-, and O-allyl-4-chlorobenzohydroxamic acids in pyridine which acted both as a solvent and a weak base. As acyl halides were used methanesulfonyl, 4-toluenesulfonyl, 4-methylbenzoyl, and 4-nitrobenzoyl chlorides. The resulting mixed anhydrides were characterized by chemical and spectroscopic methods. Thermal as well as photochemical rearrangement of the mixed anhydrides has been attempted. Structure elucidation of the rearranged products was performed by spectroscopic methods.
