Abstract

Photoirradiation of acetone solutions of 2,3‐diallyl‐6,7‐dihydro‐5__H__‐2a‐thia(2a‐S^IV^)‐2,3,4a, 7a‐tetraazacyclopent[cd]indene‐ 1,4(2__H__,3__H__)‐dithione (1) in the presence of excess thioacetic acid and thiobenzoic acid afforded addition products, 2,3‐bis(3‐acetylthiopropyl)‐ and 2,3‐bis(3‐benzoylthiopropyl)‐6,7‐dihydro‐5__H__‐2a‐thia(2a‐S^IV^)2,3,4a, 7a‐tetraazacyclopent[cd]indene‐1,4(2__H__,3__H__)‐dithiones, respectively, in good yields. These photoaddition reactions were facilitated by the addition of oxygen.

## Abstract Substituted 1‐acetonaphthones 6b–d and 2‐morpholinoacrylonitrile (2a) undergo a photocycloaddition. The type of addition ([2 + 2] vs. [4 + 2]) is dependent on the location of additional substituents. Whereas compound 6c with a methoxy group at C‐2 gave only the [4 + 2]‐cycloadduct 11, t
