temperature and decomposed gradually to form 1,2-dibenzylidenehydrazine. The plausible mechanism of the reaction is discussed. Because it was stable for a period of time, a convenient and effective method for synthesis of 1-alkyl-1,6-dihydro-1,2,4,5-tetrazines has been developed. The starting 1,6-dihydro-1,2,4,5-tetrazine can be alkylated with alkyl halides in methanol and lithium hydroxide monohydrate
摘要 6-甲基-3-苯基-1,6-二氢-1,2,4,5-四嗪常温下在碱溶液中稳定,逐渐分解生成1,2-二亚苄基肼。讨论了该反应的合理机制。由于它在一段时间内是稳定的,因此开发了一种方便有效的合成1-烷基-1,6-二氢-1,2,4,5-四嗪的方法。起始的 1,6-二氢-1,2,4,5-四嗪可以在室温下在甲醇和氢氧化锂一水合物作为碱中用烷基卤化物烷基化。
