Description

MilliporeSigma Sigma Organics products encompass a wide range of quality reagents, solvents, catalysts, and building blocks for organic synthesis. From benchtop discovery to process development and scale-up, Sigma Organics solutions are built to meet the needs of synthetic chemists.

Under a dual catalytic copper/photoredox manifold, the Mes-Umemoto reagent has been demonstrated by the MacMillan lab to be an excellent reagent for the trifluoromethylation of alkyl halides and aryl halides to yield alkyl-CF3 and aryl-CF3 in high yields. In both cases, these reactions exhibit wide substrate scope with good functional group tolerance. More specifically, a variety of 5-membered and 6-membered heteroaryl halides can be readily converted to the corresponding trifluoromethylheteroarenes under mild conditions. To be use in conjunction with supersilanol (902489) and Ir photocatalyst (902217 or 902225).A radical approach to the copper oxidative addition problem:Trifluoromethylation of bromoarenes
