Interpretation Introduction

Interpretation:

The structures for compound 1, 2 and 3 in the reaction scheme should be identified.

Concept Introduction:

Hydroboration:

Hydroboration is the addition of a hydrogen-boron bond to the Carbon-Carbon, Carbon-Nitrogen, and Carbon-Oxygen double bonds and Carbon-Carbon triple bonds.

When alkene undergoes hydroboration using alkyl borane and hydrogen peroxide followed by hydrolysis which yields the alcohol. The formation of alcohol is depends on the less hindered carbon of the double bond.

Alkyl boranes are generated by hydroboration of alkenes in presence of reagent namely $\text{9-BBN}$.

Suzuki reaction: It involves coupling of an aryl, a benzyl or vinyl halide with organoborane in presence of ${\text{Pd(PPh}}_{\text{3}}{\text{)}}_{\text{4}}$.
