N-Methylthiophthalimide undergoes photochemical cycloaddition reactions with diphenylacetylene, hex-3-yne and bis(methylthio)acetylene to form spiro-thietes; in solution the spiro-thiete from the bis(methylthio)alkyne is in equilibrium with its ring-opened isomer.

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.
