This event came from a public calendar feed. Calendar feeds publish when a show happens, not when its tickets go on sale — so this is genuinely unknown rather than zero, and rather than “already on sale”.
What the source said
Boron cations in the activation of C–H and C–C bonds The activation of aryl C–H and C–C bonds generally relies on transition-metal complexes. In recent years, frustrated Lewis pair (FLP) chemistry has enabled the development of numerous metal-free catalytic systems for aryl C–H bond activation. Nevertheless, such systems are limited to electron-rich arenes. Recently, we have prepared a series of o-carboranyl-substituted boron cations and found that these highly Lewis-acidic boron cations can catalyze C–H borylation/silylation of unactivated arenes, as well as the hydrogenolysis of C(aryl)–C(alkyl) bonds in alkylarenes. In this lecture, the reaction mechanisms of these transformations and the related boron-cation chemistry will also be discussed.
