In this study a straightforward and efficient approach concerning synthesis of 1,3-diazole derivatives under ultrasound (US) irradiation as well as under conventional thermal heating (TH) is presented. N-alkylation under US irradiation may be considered environmentally friendly in terms of higher yields, smaller amounts of solvent used and an overall energy efficiency due to a substantial reduction
在这项研究中,提出了一种简单有效的方法,涉及在超声(US)辐射以及常规热加热(TH)下合成1,3-二唑衍生物。由于反应时间的大幅减少,在更高的收率,更少的溶剂用量和总体能源效率方面,美国辐射下的N-烷基化可被认为对环境无害。进行了超声与常规条件的对比研究。总体而言,事实证明,使用US比使用TH更有效。提出了关于咪唑和苯并咪唑在美国辐射下N1-烷基化反应中不同行为的可能解释。
