• 3,4,5,6-Tetraphenylpyridazine 1-oxide (II) was irradiated in acetone or dichloromethane with high pressure mercury lamp (200W) for 3 hr, affording tetraphenylfuran (III), dibenzoylstilbenes (IV and V), 1-(1,2,3-triphenylcyclopropenyl)-⊿^<3,6>-bicyclo [3,2,0]-heptadien-2-one (VI), and the deoxygenated starting material (I). 3,4,6-Triphenylpyridazine 1-oxide (VIII) gave triphenylfuran (IX), cis-dibenzoylstyrene (X), 3-benzoyl-1,2-diphenyl-1-cyclopropene (XI), and the deoxygenated starting material (VII). The reaction mechanism is also discussed.
