A green and efficient synthesis method of benzotriazole N-alkylated derivatives was introduced using glycerol as a solvent. The method is convenient and efficient, which is suitable for a series of alkyl halides and the corresponding N-alkylated products have excellent yield. Moreover, this method is environment friendly with easy product separation and the glycerol can also be recycled.%以甘油为溶剂介绍了一种绿色、高效的苯并三氮唑N-烷基化衍生物的合成方法。该方法简便有效，适用于一系列的烷基卤代物，均能得到相应的N-烷基化产物且收率较高。此外，这种方法对环境无害，产品易分离，且能实现甘油的回收利用。
