Aplicação
Under a dual catalytic copper/photoredox manifold, this supersilanol 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 dMesSCF3 (901466) and Ir photocatalyst (902217 or 902225).

Mo and W MonoAryloxide-Pyrrolide (MAP) olefin metathesis catalysts can couple terminal olefins to give as high as >98% Z-products in moderate to high yields with as little as 0.2% catalyst. Results are reported for 1-hexene, 1-octene, allylbenzene, allyltrimethylsilane, methyl-10-undecenoate, methyl-9-decenoate

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
