Application

Under a dual catalytic copper/photoredox manifold, the Mes-Umemoto reagent has been demonstrated to be an excellent photocatalyst 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. For trifluoromethylation reactions, use with dMesSCF3 (901466) and supersilanol (902489).

Product can be used with our line of photoreactors: Including Penn PhD (Z744035) & SynLED 2.0 (Z744080)

Despite advances in hydrogen atom transfer (HAT) catalysis, there are currently no molecular HAT catalysts that are capable of homolysing the strong nitrogen-hydrogen (N-H) bonds of N-alkyl amides. The motivation to develop amide homolysis protocols stems from the utility of

Transition metal-catalyzed arene functionalization has been widely used for molecular synthesis over the past century. In this arena, copper catalysis has long been considered a privileged platform due to the propensity of high-valent copper to undergo reductive elimination with a
