โœฆ Synopsis

Irradiation of g-allqrlbenzophenones (I) results in formation of photoenols (II), which revert to the parent ketones in the dark.* 2,5-Dimethylaaetophenone also gives a aorrespending photoenoi, but is slowly aonverted into presumably a pinacol. 3 It appeared interesting to examine photochemical behaviors of highly hindered aromatic ketones, such aa III, which might be difficult to photoenolize because of a ateria hindrauoc,4 We wish to report the first example of benzoayalobutauol formation from 2-nethylphenyl ketones and 8 fragmentation reaction.
