Diphenylketene undergoes photocycloaddition with N-methylthiophthalimide, N-methyldithiophthalimide or xanthene-9-thione, to give a spiro-adduct containing a thietan-2-one ring.The photoproducts from the thioimide substrates are themselves photolabile, eliminating COS to form an alkene.Diphenyl-N-(p-tolyl)ketenimine gives analogous 2-iminothietanes on irradiation with the thioimides.
