WebJan 28, 2024 · The best way to depict the acid-catalyzed epoxide ring-opening reaction is as a hybrid, or cross, between an S N 2 and S N 1 mechanism. First, the oxygen is protonated, creating a good leaving group (step 1 below). Then the carbon-oxygen bond begins to break (step 2) and positive charge begins to build up on the more substituted carbon. Webn-Butyllithium C 4 H 9 Li (abbreviated n-BuLi) is an organolithium reagent.It is widely used as a polymerization initiator in the production of elastomers such as polybutadiene or styrene-butadiene-styrene (SBS).Also, it is broadly employed as a strong base in the synthesis of organic compounds as in the pharmaceutical industry..
