accurate control of the reaction parameters realized within microreactor systems allowed for a taming of the reactivity of thermally unstable intermediates such as haloalkyllithiums. The first example of effective external trapping of a reactive carbenoid such as the chloromethyllithium is described. By using microreactor systems, a continuous flow synthesis of chloro alcohols and chloro amines could be
这项工作表明,在微反应器系统内实现对反应参数的精确控制,可以控制热不稳定中间体(如卤代烷基锂)的反应性。描述了有效的外部捕获类胡萝卜素(例如氯甲基锂)的第一个例子。通过使用微反应器系统,可以高产率实现氯醇和氯胺的连续流合成。通过控制停留时间,可以生成高反应性的氯甲基锂,并使之与亲电试剂在比分批模式高得多的温度下反应,并且无需内部淬火。已开发的连续流程符合可持续性要求。
