• Photolyses of various diazine N-ethoxycarbonylimides (3,9,and 19), prepared from the corresponding diazines (1,8,and 17), resulted in the formation of the pyrazole derivatives (4 and 10) from pyrazine and pyrimidine N-imides, and of the pyrrole derivatives (20) from pyridazine N-imides. These photolyses may proceed by rearrangement to diaziridine intermediates, followed by ring expansion to the corresponding 1,2,5-, 1,2,4-, or 1,2,3-triazepines (6,12,or 22), which then undergo isomerization to the triaza[3.2.0]bicycloheptadienes (7,13,and 23), followed by elimination to give the products (4,10,and 20,respectively).
