Cyclic isoimidium perchlorates derived from N,N-diethylphthalamic acid and the monomorpholides of succinic and maleic acid react with benezene, toluene or anisole in the presence of aluminium chloride to give the corresponding ß-aroylcarboxamides in moderate yields.

A rhodium-catalyzedoxidative acylation of benzamides with aryl aldehydes via direct sp2 C–Hbond cleavage is described. In the presence of [Cp*RhCl2]2, AgSbF6, and silver carbonate as an oxidant, N,N-diethyl benzamides can be effectively carbonylated to yield ortho-acyl benzamides.
