Photolysis of 3‐phenyl‐2, 1‐benzisoxazole and some derivatives in hydrobromic acid The behaviour of 3‐phenylanthranils (3‐phenyl‐2, 1‐benzisoxazoles) towards photolysis in hydrobromic acid differs greatly from that in hydrochloric and sulfuric acid. Thus, reduction and substitution products are obtained. The formation of the reduction products involves hydrogen abstraction by a nitrenium ion species in the triplet state and that of the substitution products can be attributed to a subsequent S E ‐bromination.
