The photobromination of CH bonds by using molecular bromine was reinvestigated under microfluidic conditions. The continuous‐flow method suppressed the production of dibrominated compounds and effectively produced the desired monobrominated products with high selectivity. Rapid bromination of benzylic substrates containing a photoaffinity azide group was achieved without any decomposition.
C的photobromination H键通过使用分子溴在微流体条件下重新调查。连续流方法抑制了二溴化合物的生产,并以高选择性有效地生产了所需的单溴产品。含有光亲和性叠氮化物基团的苄基底物可以快速溴化,而不会分解。
