Abstract
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. N Alkylation of 1,2,3 benzotriazole catalyzed by KF/Al 2O 3 was studied.Be nzotriazole reacted with alkyl halides on KF/Al 2O 3 in DMF at 30 ℃ for 1 h, giving N 1 and N 2 substituted benzotriazoles in yield of 57%～95%.
