研究了用固体碱ＫＦ／Ａｌ２Ｏ３为缚酸剂，ＤＭＦ为溶剂，以卤代烃为烷基化剂实现１，２，３－苯并三唑Ｎ－烷基化反应．不同的卤代烃，得到不同比例Ｎ１及Ｎ２烷基化产物，烷基化产率在５７％～９５％之间．
The N, N-alkylation of 1,2,3-benzotriazole with solid base KF / Al2O3 as acid-binding agent, DMF as solvent and halogenated hydrocarbon as alkylating agent were studied. Different halogenated hydrocarbons, obtained in different proportions of N1 and N2 alkylation products, alkylation yield between 57% ~ 95%.
