Flash vacuum pyrolysis of 3-methylsulfanyl-1,2,4-benzotriazine N-oxide, 3-methylsulfanyl-1,2,4-benzotriazine, and 3-phenyl-1,2,4-benzotriazine are described. The N-oxide derivative underwent deoxygenation between 500 and 600°C, whereas at higher temperatures both methylsulfanyl compounds, besides yielding the same products, also gave benzimidazole formed by an independent mechanism. Transformation
描述了3-甲基硫烷基-1,2,4-苯并三嗪N-氧化物,3-甲基硫烷基-1,2,4-苯并三嗪和3-苯基-1,2,4-苯并三嗪的快速真空热解。的Ñ 500和600之间氧化物衍生物后行脱氧℃,而在较高温度下都甲硫化合物,除了产生相同的产品,也给了苯并咪唑由一个独立的机构形成。这些衍生物在600到750°C之间的转化导致形成复杂的反应混合物,表明该过程的根本性质。在575至650°C之间研究了苯基取代的衍生物,得到苯甲腈和痕量的联苯。
