arise from different reagents. Our studies show that the reaction mechanism is similar to the Hooz multicomponent coupling. The process involves in situ generation of BAr3, which reacts with a diazocarbonyl compound, and the reaction is terminated by an electrophilic SCF3 transfer. The reaction can also be extended to fluorination based bifunctionalization which proceeds with somewhat lower yield than
开发了一种新的基于锌介导的三氟甲基硫醇化的双官能化反应。在此过程中,同时发生的C–SCF 3和C–C键形成多组分反应,其中芳基和SCF 3基团来自不同的试剂。我们的研究表明,反应机理与Hooz多组分偶联相似。该方法涉及原位产生BAr 3,其与重氮羰基化合物反应,并且该反应通过亲电SCF 3转移而终止。该反应还可以扩展到基于氟化的双官能化,与相似的三氟甲基硫醇化反应相比,该双官能化的产率略低。
