Demercuration mechanism

WebThe mechanism with mercury catalysis is very similar. The main difference is that the initial intermediate is a mercurinium ion, which is opened by the nucleophilic attack of water at the more substituted site. Beyond that, … WebAcid-Catalyzed Addition of an Alcohol Mechanism. Step 1: The pi electrons of the alkene attack a hydrogen of the protonated alcohol* resulting in carbocation formation. The carbocation is a high energy intermediate making this the rate determining step (slow step) of …
