Flash vacuum pyrolysis of the dimethylamino-azapropenones (7)-(9) and -azapropenethione (12) gives nitriles and amides (or thioamide) in yields of ca. 30percent by an electrocyclisation-ring cleavage mechanism.This is a minor pathway for the triarylazapropenones (14) and (15) for which homolytic cleavage of the C-N bond gives rise to the major products.The X-ray crystal structures of (10) and (12) show that the conjugated systems are almost planar in the s-Z conformation, as required for the electrocyclic ring closure.
