N-Arylaroylacetamides and 4-aryl-1,5-benzodiazepin-4-ones were obtained by the thermolysis of 2,2-dimethyl-6-aryl-1,3-dioxin-4-ones in the presence of aromatic amines and o-phenylenediamine respectively.Investigetion of the reaction kinetics showed that the controlling stage is the generation of the aroylketenes, which takes place by a concerted -retrocycloaddition mechanism.
