## Abstract Dihydrothiinone **9a** undergoes photocycloaddition regioselectively to all three CC bonds of penta‐1,2,4‐triene (**10**), the relative stabilities of the biradical intermediates determining the product distribution. In contrast, cyclohexenone **9b** and dihydropyranone **9c** afford m
## Abstract On irradiation, in the presence of 2,3‐dimethylbuta‐1,3‐diene, naphthalen‐2‐ones **1** are quantitatively and regioselectively converted to mixtures of diastereoisomeric cyclobutane adducts **3** and **4**, whereas, under these conditions, 3‐(alk‐1‐ynyl)cyclohex‐2‐enones **5** give only
