Photochemical reaction of tetracarbonyl(6-7-η-4-phenyl-2-oxa-3-azabicyclo[3.2.0]hepta-3,6-diene)iron to give 2-phenylpyridine and 2-formyl-5-phenylpyrrole was studied. Furthermore, photochemical and thermal reactions of tetracarbonyl(6-7-η-2-ethoxycarbonyl-2,3-diazabicyclo[3.2.0]hepta-3,6-diene)iron were found to undergo decomplexation, N-N bond cleavage leading to 1-(N-ethoxycarbonyl)amino-4-cyano-1,3-butadiene, and dimerization of the cyclobutene moiety incorporating carbonyl group.
