✦ Synopsis

Earlier studies have demonstrated that many conjugated cyclopropyl ketones are converted 3 to a,b-unsaturated ket nes when subjected to ultraviolet irradiation.

Considerable mechanistic rationale is currently being applied to an understanding of the factors which control the 4 direction of cyclopropyl ring cleavage under these conditions.

We have now extended our study of the photochemical behavior of unsaturated medium-sized ring ketones 3,5
