yields in shorter reaction times. This decreases total ‘man-hours’ in a synthetic setting. Another technique used in organic chemistry to decrease manual manipulations, is solid support reagents. The benefits of this approach is that upon completion of a reaction, a simple filtration can be performed which expedites the work-up and also produces less organic waste. Friedel-Crafts alkylation has been
微波辐射是有机合成中一种流行的方法,可以在较短的反应时间内获得高产率。在综合环境中,这减少了总的“工时”。用于有机化学中以减少手动操作的另一种技术是固体支持试剂。这种方法的好处是,反应完成后,可以进行简单的过滤,从而加快了后处理的速度,并且减少了有机废物的产生。已使用微波化学方法以及固体支持试剂探索了Friedel-Crafts烷基化反应。与传统加热以及AlCl 3相比,当仅用微波照射5分钟时,硅胶键合的氯化铝(Si-AlCl x)观察到较高的收率。
