The flashvacuumpyrolysis of 1-(2-ethoxycarbonylethenyl)benzotriazole hasbeen reinvestigated, and the processes leading to the formation of ethylindole-3-carboxylate and 2-ethoxyquinolin-4(1H)-oneelucidated. Similar pathways are followed in the flashvacuumpyrolysis of thecorresponding benzisoxazolone. SomeN-ethenylisoxazolones have been pyrolysed to formpyrroles, but rearrangement of the intermediate
