Question

How can propan 1ol be prepared from propene with the help of hydroborationoxidation reaction with chemical reaction?

Answer 1

Hello friend,

# Hydroboration-oxidation -

The addition of borane followed by oxidation is known as the hydroboration-oxidation reaction.

# Propene→Propan-1-ol-

Propene is converted to propan-1-ol by hydroboration-oxidation.

Initially, propene reacts with diborane to form trialkyl borane as addition product.

CH3-CH=CH2 + (BH3)2 → CH3-CH(H)-CH2(BH2)

CH3-CH(H)-CH2(BH2) + CH3-CH=CH2 → (2CH3-CH-CH2)2-BH

(2CH3-CH-CH2)2-BH + CH3-CH=CH2 → (2CH3-CH-CH2)3-B

This addition product is oxidized to alcohol by hydrogen peroxide in the presence of aqueous sodium hydroxide

(2CH3-CH-CH2)3-B + 3H2O2 + 6OH- → 3CH3-CH-CH2-OH + B(OH)3

Hope you got it...
