Interpretation Introduction

Interpretation:

The structures of product formed in each of the given reaction are to be written.

Concept introduction:

Carbonyl dichloride, when treated with alcohol equivalent to one molar quantity, forms alkyl chloroformate. It reacts with ammonia or amines to form carbamates or urethanes. These carbamates are also formed when acyl isocyanate reacts with a higher-level alcoholic group and undergoes decomposition in the presence of ${\text{H}}_2/\text{Pd}$, or with ${\text{HBr/CH}}_3{\text{CO}}_2\text{H}$ under a mild condition to form amides. This reaction is called de-protection.
