Abstract

Upon UV-irradiation in chloroform solution, some of the 2,4,4,6-tetrasubstituted-4H-thiopyran-1-oxides underwent deoxygenation to give the corresponding 4H-thiopyrans in good yields together with the corresponding 4Hthiopyran- 1,1-dioxides as minor components. Moreover, in benzene as an aromatic solvent oxenoid functionalization was observed.

Keywords: 4H-Thiopyran-1-oxides, photodeoxygenation, oxenoid functionalization
