The direction of the reactions of substituted ethylene thiolates with nitrile imines and hydrazonoyl chlorides depends on the nature of the substituents.Thus, 1-dialkylamino-substituted thiolates form only cyclic products, e.i., 5,6-dihydro-4H-1,3,4-thiadiazines and 4H-1,3,4-thiadiazines.Potassium 1-methylthio-2-phenylethenethiolate, on the other hand, gives only the linear product from nucleophilic substitution of the chlorine atom.Electron-withdrawing substituents at position 2 of the ethylene thiolates do not reduce their capacity for cycloaddition, and potassium 1-methyl-2-ethoxycarbonylethenethiolate with ethyl phenylhydrazonochloroacetate forms 2-acetyl-6-methyl-4-phenyl-5-ethoxycarbonyl-5,6-dihydro-4H-1,3,4-thiadiazine.

The reaction of potassium 2-phenylethynethiolate with N-arylhydrazonoyl chlorides in the presence of triethylamine leads to the formation of 2,4,5-trisubstituted 4H-1,3,4-thiadiazines.Without triethylamine the reaction leads to the quantitative formation
