3-Substituted 3,4-dihydro-4-imino-1,2,3-benzotriazine derivatives 7 were formed from 2-azidobenzonitriles 4 as starting materials on treatment with Grignard or lithium organic reagents. In some cases these procedures gave aryltriazenes 10 and 11 as products. All compounds were identified by NMR spectroscopy and the structures of three products, namely 7a, 10a and 11i, were corroborated by X-ray crystallography
3-取代的 3,4-二氢-4-亚氨基-1,2,3-苯并三嗪衍生物 7 由 2-叠氮苯甲腈 4 作为起始原料,用格氏试剂或锂有机试剂处理形成。在某些情况下,这些程序得到芳基三氮烯 10 和 11 作为产物。所有化合物均通过 NMR 光谱鉴定,三种产物的结构,即 7a、10a 和 11i,通过 X 射线晶体学得到证实。
