1-Vinylbenzotriazoles give indoles on flash vacuum pyrolysis, but depending on the vinyl substituents side reactions leading to N-phenylketenimines or benzonitrile are observed. The latter process occurs with 1,2-disubstituted vinyl groups and an azatrimethylenemethane is suggested as an intermediate. Ketenimine formation is associated with vinyl groups bearing an α-hydrogen and is the only pathway
