WebIn the previous post, we talked about the acid-catalyzed hydration of alkenes where an alcohol is formed as the major organic product:. If an alcohol, rather than water, is used as the solvent a very similar reaction takes place and an ether is produced. Just like the hydration, it goes through a stepwise mechanism starting with the protonation of the … WebThe Hydroboration Oxidation reaction is an organic chemical reaction which is employed for the conversion of alkenes into alcohols that are neutral. This is done via a two-step process which includes a hydroboration step and an oxidation step. This is done by a net addition (across the entire double bond) of water.

WebOxymercuration-Demercuration. In the previous post, we talked about the acid-catalyzed hydration of alkenes which leads to the formation of alcohols:. Let’s quickly recall the mechanism. The reaction starts with protonation of the double bond which leads to the more stable carbocation. WebThe two alcohol molecules involved in the reaction play two roles—one alcohol molecule acts as a substrate while the other acts as a nucleophile. The reaction follows an S N 2 mechanism.
