draw the product(s) of the following hydroboration-oxidation reactions. Disregard stereochemistry
This problem is based on the concept of hydroboration-oxidation of alkenes.
Hydroboration reaction involves the oxidation reaction of alkenes by using diborane which gives a organoboron compound which on further reaction with sodium hydroxide in the presence of hydrogen peroxide gives a alcoholic compound.
Diborane on reaction with alkene gives a organoboron which is formed by the process of replacement of hydrogen atoms in boron compound by organic molecules. This organoborane compound is highly reactive towards alkaline solution of hydrogen peroxide and gives alcohol.
