Abstract:Reactive intermediates are key to halting and promoting chemical transformations, however due to their elusive nature, they are seldom harnessed for reaction design. Herein, we describe studies aimed at stabilizing reactive intermediates in the N-heterocyclic carbene (NHC) catalytic cycle, which enabled fully shutting down the known benzoin coupling pathway, while rerouting its intermediates toward deuteration. The reversible nature of NHC catalysis and the selective stabilization of reaction intermediates fac… Show more
