โฆ Synopsis
It was recently reported that the acetone-sensitized photoisomerisation of anti-7,8-beneotricyclo[4.2.2.0295 ]deca-3,7,9-triene (1) yields beneobasketene (2) and tetracyclic isomer (3).1
We now wish to describe our related studies on the photosensitiaed isomerization of (1) and some related compounds.
