Photochemical reactions of various N-(α,β-unsaturated carbonyl)benzoylformamides both in solution and in a solid state were investigated. Under homogeneous conditions, all acyclic imides underwent photochemical 2 + 2 cycloaddition that resulted in

Photocyclization reactions of δ-hydroxybutyl α,β-unsaturated γ,δ-epoxy nitriles 4a, b at 254 nm lead to spiro ketals 5a, b and 6a, b arising from the carbonyl ylide intermediate A. The spiro ketal 6b containing an endocyclic double bond is trans

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-s

Tetraethylethanediselenoamide (2) was prepared in 81% yield by reaction of tetraethylethynediamine with elemental selenium. The X-ray single crystal structure analysis revealed that two Et2N(C=Se)– units of 2 are perpendicular to each other. The ox
