WebMar 30, 2024 · So far hidden competing reaction pathways may limit the maximum stereoselectivities and the potential of prediction models. In CPA catalyzed transfer hydrogenation of imines, we identified for many systems two reaction pathways with inverse stereoselectivity, featuring as active catalyst either one CPA or a hydrogen bond bridged … WebJan 28, 2024 · In the first step of the reaction mechanism, one alcohol is protonated to become a good leaving group. In the second step, a second alcohol displaces water from the protonated alcohol during an S N 2 reaction yielding a protonated ether. In the final step, this intermediate is deprotonated to yield the symmetrical ether. Williamson Ether Synthesis
