DISCOVERY of the profound molecular changes involved in the photodhemical conversion of santonin (I) to photosantonic acid (II),l the structure of n which was established in this Laboratory," prompted broader investigation I i1 of carboxylic acid production by ultraviolet irradiation of cross-conjugated dienones. The abnormal Reimer-Tiemann reaction product III represents an interesting variant; and we have now found that this dienone is transformed 0 c&3 0 I I I&c cm12 III la F.
