Name the major product formed when sodium phenoxide is heated with `CO_(2)` at 400K under 4-7 atm pressure. What is the name of the reaction?

Explanation

To solve the question, we need to analyze the reaction between sodium phenoxide and carbon dioxide (CO2) under specific conditions. Here’s a step-by-step breakdown of the solution:

### Step 1: Identify the Reactants
The reactants in this reaction are sodium phenoxide (C6H5O-Na+) and carbon dioxide (CO2). Sodium phenoxide is the sodium salt of phenol, and it has a phenoxide ion (C6H5O-) that is a strong nucleophile.

**Hint:** Look for the structure of sodium phenoxide and understand its nucleophilic nature.

### Step 2: Understand the Reaction Conditions
