substituted benzenediazonium tetraphenylborates to form 1,2,4,3λ4-triazaborines or 1,3,2λ4-oxazaborines. The formation of either the first or the second product is affected by the reaction conditions, especially by the presence of water in the reaction components and in the solvent. If the reaction is performed under anhydrous conditions, the major product is the triazaborine. When ‘wet’ diazonium salts are
β-Enaminonitriles与取代的苯重氮四苯基硼酸盐反应,以形成1,2,4,3λ 4 -triazaborines或1,3,2λ 4 -oxazaborines。第一或第二产物的形成受反应条件的影响,特别是受反应组分和溶剂中水的存在的影响。如果反应在无水条件下进行,则主要产物是三氮杂萘灵。当使用“湿”重氮盐或将少量水添加到反应混合物中时,恶唑茶碱就是产物。
