The photolysis of spiro[benzo[<I>b</I>]thiophene-2(3<I>H</I>),1′-cyclopropan]-3-one 1,1-dioxide (<B>1</B>) in benzene afforded 2-biphenylyl cyclopropyl ketone with extrusion of sulfur dioxide, whereas the irradiation of <B>1</B> in toluene or <I>p</I>-xylene formed photoreduced dimer and bibenzyl or 4,4′-dimethylbibenzyl, respectively. The photolysis of spiro[benzo[<I>b</I>]thiophene-2(3<I>H</I>),1′-cyclopropan]-3-one in benzene afforded the valence isomer 2,3-dihydro[1]benzothieno[3,2-<I>b</I>]furan.
