Abstract 3-Azido-5,6-diphenyl-1,2,4-triazine (1) and 3-azidophenanthro[9,10-e]-1,2,4-triazine (2) are synthesized in high yield (∼75%). 1 and 2 react with triphenylphosphine to afford phosphazenes 5 and 6 with a covalent structure. Reactions of 1 and 2 with trialkylphosphites 3b, c produce phosphazenes 7a, b and 8a, b which have the phosphonium dipolar ion structure, 1 reacts with diethyl phosphonate
摘要 3-叠氮基-5,6-二苯基-1,2,4-三嗪 (1) 和 3-叠氮菲 [9,10-e]-1,2,4-三嗪 (2) 以高产率合成 (∼ 75%)。1和2与三苯基膦反应得到具有共价结构的磷腈5和6。1和2与亚磷酸三烷基酯3b、c反应生成磷腈7a、b和8a,b具有鏻偶极离子结构,1与膦酸二乙酯(4a)反应得到氨基磷酸酯10a。在与膦酸二甲酯反应时解离为相应的胺 11。提出了形成新加合物的可能反应机制。
