Chapter 26, Problem 26.56P
Interpretation Introduction

(a)

Interpretation: The explanation for the conversion of A to B is to be stated.

Concept introduction: Alkene metathesis generally known as olefin metathesis occurs in the presence of Grubbs catalyst. The ring-closing metathesis (RCM) by Grubbs catalyst occurs if the starting material is diene. This reaction is facilitated under the high-dilution condition as it favors intramolecular metathesis instead of intermolecular metathesis.

Interpretation Introduction

(b)

Interpretation: The two products formed by dienyne metathesis of C are to be drawn.

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