Reactions of 1,2,4-triazole-3-thiols with 2-bromopropionic acid, 2-bromocaproic acid, ethylene chlorohydrine, chloroacetamide, 3-bromo-4-methoxybenzyl chloride, 2-methoxy-5-acetylbenzyl chloride, and 2-(2-chlorophenoxy)ethyl chloride in the presence of KOH have afforded new 3-sulfanyl-1,2,4-triazoles in high yields. Aminomethylation of 1,2,4-triazole-3-thiols in the presence of formaldehyde has given
1,2,4-三唑-3-硫醇与2-溴丙酸,2-溴己酸,乙烯氯醇,氯乙酰胺,3-溴-4-甲氧基苄基氯,2-甲氧基-5-乙酰基苄基氯和2-的反应在KOH存在下的(2-氯苯氧基)乙基氯以高收率提供了新的3-硫烷基-1,2,4-三唑。在甲醛存在下1,2,4-三唑-3-硫醇的氨甲基化反应产生了相应的2-氨基甲基-2 H -1,2,4-三唑-3(4 H)-硫酮。三唑-3-硫醇与福尔马林和丙烯腈的相互作用导致形成N 2-羟甲基-和3-(2-氰基乙基)硫烷基衍生物。
