In order to synthesize a variety of 4-amino-6-substituted amino-2-substituted symtriazine, 1-substituted biguanide was allowed to react with ethyl chloroacetate to give 4-amino-6-substituted amino-2-chloromethyl-sym-triazine, from which the purpose compounds were derived. The reactions of 4-amino-6-substituted amino-2-chloromethyl-symtriazine with amines and alkylthiols were successfully carried out to give 4-amino-6-substituted amino-2-substituted aminomethyl-sym-triazine and 4-amino-6-substituted amino-2-alkylthiomethyl-sym-triazine, respectively. However, in the reaction with sodium alkanethiosulfonate, it was found to result in the formation of the corresponding sulfone afforded by the partial desulfurization in the intermediately formed 4-amino-6-substituted amino-2-methoxythiosulfonyl-sym-triazine. This sulfone was confirmed to be identical with that obtained by oxidation of the corresponding sulfide. The mercaptylation of 4-amino-6-piperidino-2-chloromethyl-sym-triazine with thiourea was resulted in the formation of the corresponding disulfide rather than the thiol compound anticipated.
为了合成多种4-氨基-6-取代氨基-2-取代对称三嗪,1-取代双脲与氯乙酸乙酯反应,生成4-氨基-6-取代氨基-2-氯甲基对称三嗪,从中衍生出目标化合物。4-氨基-6-取代氨基-2-氯甲基对称三嗪与胺及烷基硫醇的反应成功进行,分别生成4-氨基-6-取代氨基-2-取代氨基甲基对称三嗪和4-氨基-6-取代氨基-2-烷基硫甲基对称三嗪。然而,在与烷基硫酸钠的反应中,发现形成了相应的磺酮,这是由于部分脱硫在中间生成的4-氨基-6-取代氨基-2-甲氧基硫代磺酸基对称三嗪中发生的。这种磺酮被确认与通过氧化相应的硫化物获得的磺酮相同。4-氨基-6-哌啶基-2-氯甲基对称三嗪与硫脲的反应形成了相应的二硫化物,而不是预期的硫醇化合物。
