(a)

Interpretation Introduction

Interpretation:

The structures of requisite aryl iodide, boronic acid and compound B in the given reaction should be determined.

Concept Introduction:

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

(b)

Interpretation Introduction

Interpretation:

The reason that supports why compound A undergoes cross couples with aryl iodide but not with 2 molecules of A coupling should be identified.

Concept Introduction:

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