The photochemical cycloaddition of acetylene to benzene and its simple derivatives leading ultimately to cyclooctatetraenes has enjoyed rather limited applicability. Previously, successful examples were confined to electron deficient acetylenes or activated aromatic systems.' Very recently, Bryce-
Diarylthioketones 1,2 , thiophosgene3, and thione carbonates 4 react with substituted alkenes under photochemical conditions to give thietanes and in some cases, 1,4-dithianes. It is known that thioparabanates, A, undergo photoreduction in ethanolic solution5. However, the formation of a small amoun
