Chapter 26, Problem 26.46P

Interpretation Introduction

(a)

Interpretation: The product formed from the ring-closing metathesis of given compound is to be drawn, and the synthesis of metathesis starting material using ${\text{CH}}_{\text{2}}{\left({\text{CO}}_{\text{2}}\text{Et}\right)}_{\text{2}}$, alcohols with less than five carbons, and any needed organic and inorganic reagents is to be stated.

Concept introduction: The ring-closing metathesis (RCM) by Grubbs catalyst occurs, when the starting material is diene. This reaction is facilitated under high-dilution condition as it favors intramolecular metathesis instead of intermolecular metathesis.
