Abstract
Spironaphthalenones 1a–g & 1j–m on irradiation, with UV light gives the isomeric spironaphthalenones 2a–g & 2j–m in almost quantitative yield. On the other hand, spironaphthalenones 1h, 1i, 1n & 1o photoisomerized to the isomeric spironaphthalenones in reduced yields. Similar irradiation of 2a–g & 2j–m did not bring any change whereas 2h, 2i, 2n & 2o rearranged to isomeric spironaphthalenones. A probable mechanism has been proposed for this isomerization.
