The flash vacuum thermolyses of 1,2,3,4-tetrahydroquinoline 3, o-aminobenzylalcohol 4 and o-aminobenzylamine 5 were performed at temperatures from 923 to 1273 K and monitored by photoelectron spectrometry. While thermolyses at 923-1073 K led to the until now undescribed benzoazetine 2a, 6-methylene-2,4- cyclohexadien-1-imine 1a was obtained at 1173-1273 K.
