Alkylsulfanylchloroacetylenes react with 1,1-dimethylhydrazine in diethyl ether at 20–22°C to give, depending on the reactant ratio, 3,6-bis(alkylsulfanylmethyl)-1,1,4,4-tetramethyl-1,4-dihydro-1,2,4,5- tetrazine-1,4-diium dichlorides (yield 67–80%) or 1-[2-(alkylsulfanyl)-1-(2,2-dimethylhydrazono)ethyl]-1,1-dimethylhydrazinium chlorides. The latter readily undergo dequaternization to the corresponding 2-alkylsulfanyl-N 1,N 2,N 4-trimethylethanohydrazide hydrazones (yield up to 53%).
烷硫基氯乙炔与1,1-二甲基肼在20-22°C的二乙醚中反应,根据反应物的摩尔比,生成3,6-双(烷硫基甲基)-1,1,4,4-四甲基-1,4-二氢-1,2,4,5-四嗪-1,4-二氯化二铵(产率67-80%)或1-[2-(烷硫基)-1-(2,2-二甲基肼基)乙基]-1,1-二甲基肼氯。后者容易去季铵化得到相应的2-烷硫基-N1,N2,N4-三甲基乙酰肼脎(产率高达53%)。
