Photocycloaddition Reactions of Thioimides with Alkynes

Photochemical reactions between N-methyl(thiophthalimide) and diphenylethyne or hex-3-yne involves selective cycloaddition at the C=S bond, and yields a spiro-thiete product.A related spiro-1,2-dithiole isolated from the reaction mixture may be formed during the work-up procedure.With bis-(alkythio)ethynes, both N-methyl(thiophthalimide) and N-methyl(dithiophthalimide) form α-alkythio α,β-unsaturated dithioesters; such 1:1 adducts are most readily explained on the basis of initial spiro-thiete formation.
