AbstractÐ1H-2-Benzothiopyran-1-ones (isothiocoumarins) and 1H-2-benzopyran-1-ones (isocoumarins) behave dissimilarly on solid state irradiation at room temperature as the former photocyclodimerize ef®ciently while the latter only undergo slow photodecomposition. Both 4H-naphtho[2,1-c]pyran-4-one and

## Abstract The photocycloaddition of benzothiazole‐2‐thiones to electron‐rich and aryl‐substituted alkenes are described. Irradiation of __N__‐unsubstituted benzothiazole‐2‐thione (1) in the presence of alkenes 3 gave 2‐(2′‐mercaptoalkyl)benzothiazoles 4, and 2‐substituted benzothiazoles 5 and 6 (

3+2]-Photocycloadditions of 1,2-, 1,3-, and 2,3-dicyanonaphthalenes to alkenes were found to proceed at the 1,8-, 4,5-, and 1,8-positions of the naphthalene ring of dicyanonaphthalenes, respectively. In the photoreactions of the 1,3-and 2,3-isomers [3+2]-adducts were obtained in oxidized forms and a

A synthetically useful C-C bond formation involving the photochemical addition of quinoxaline-2( 1 H )thiones to alkenes is described. Irradiation of the quinoxaline-2(1H)-thiones 1 4 in the presence of the alkenes 7 gave the 2-(2'-mercaptoalkyl)quinoxalines 8 1 1 in moderate-to-good yields via ring
