Key Concepts

Alkene

An alkene is an organic compound that contains at least one carbon-carbon double bond. The presence of the double bond introduces regions of high electron density which are reactive towards electrophilic or nucleophilic addition reactions. Understanding the structure of alkenes is critical for predicting the outcome of reactions such as hydroboration-oxidation.

Hydroboration-Oxidation Reaction

Hydroboration-oxidation is a two-step reaction used to convert alkenes into alcohols. The reaction begins with the addition of borane (BH3 or its derivatives) across the double bond, followed by oxidation with hydrogen peroxide (H2O2) in the presence of a base. This reaction is favored because it proceeds under mild conditions and typically avoids carbocation rearrangements.

Anti-Markovnikov Addition

Anti-Markovnikov addition refers to the regioselectivity observed in the hydroboration step of hydroboration-oxidation, where the boron atom adds to the less substituted carbon of the alkene. Consequently, after oxidation, the hydroxyl group is found on the less substituted carbon, which is opposite to what is observed in reactions following Markovnikov’s rule.

Syn Addition

Syn addition is a stereospecific process where both the hydrogen (or the boron in the initial step) and the subsequent hydroxyl group are added from the same side of the alkene. This simultaneous addition from one face of the molecule is a key feature of the hydroboration-oxidation reaction, leading to predictable stereochemical outcomes in the alcohol product.
