In organic chemistry, the oxymercuration reaction is an electrophilic addition reaction that transforms an alkene (R2C=CR2) into a neutral alcohol. In oxymercuration, the alkene reacts with mercuric acetate (AcO−Hg−OAc) in aqueous solution to yield the addition of an acetoxymercury (−HgOAc) group and a hydroxy (−OH) group across the double bond. Carbocations are not forme… WebOxymercuration - 1. Hg (OAc) 2, H 2 O Step 1: Mercuric acetate ionizes to some extent and the pi electrons of the alkene attack a mercury cation which attacks one the of the alkene carbons back forming a three-membered ring with Hg referred to as a … lending a helping hand hub

It involves the hydration of alkenes with mercuric acetate in a mixture of tetrahydrofuran and water, forming an organomercury adduct. This is followed by a demercuration step in which the adduct is reduced to an alcohol using sodium borohydride. lending a hand women
