alkyl halides reaction proceeds at ambient temperature whereas in the cases of less reactive alkyl halides require 55–60 °C to complete alkylation process. N-alkylation induced ring opening of the heterocyclic ring in benzimidazole derivatives to multifunctional aromatic compounds were noticed at 60 °C when more than two equivalents of alkyl halide was used.

生物的N -1烷基化的可持续途径。通过抑制不同底物引起的溶解度问题,将
SDS掺入反应介质中可提高反应速率。该方法在较短的反应时间内提供了高产率的烷基化产物。对于反应性烷基卤,反应在环境温度下进行,而对于反应性较低的烷基卤,则需要55–60°C才能完成烷基化过程。当使用多于两个当量的烷基卤时,在60℃下观察到N-烷基化引起的
