Alkenes can be hydrated via the addition of borane to yield alcohols with non-Markovnikov regiochemistry
Alkenes can be hydrated via the addition of borane to yield alcohols with non-Markovnikov regiochemistry. The boron atom is an electrophile and thus follows Markovnikov's rule in adding to the carbon containing the most hydrogens. Oxidation of the alkylborane with basic peroxide yields the product alcohol. Draw curved arrows to show the movement of electrons in this step of the mechanism. Alkenes can be hydrated via the addition of borane to yield alcohols with non-Markovnikov regiochemistry. The boron atom is an electrophile...
