Two approaches have been developed for the regiospecific continuous‐flow synthesis of 1‐substituted benzotriazoles. They begin with either an SNAr reaction at high temperature or Pd catalysis and involve consecutive multiphase processes, allowing the multistep synthesis of benzotriazoles to take place in an efficient manner (see picture).
已经开发出两种方法用于1-取代的苯并三唑的区域特异性连续流动合成。它们从高温下的S N Ar反应或Pd催化开始,并且涉及连续的多相过程,从而可以高效地进行苯并三唑的多步合成(见图)。
