Chapter 23.9, Problem 32ATS

(a)

Interpretation Introduction

Interpretation:

The coupling product obtained by treating the given compound with Grubbs catalyst should be identified.

Concept Introduction:

Grubbs catalyst: This catalyst is used to achieve alkene metathesis.  It contain transition metal namely $\text{Ru}$ which is doubly bonded with carbon atom.

  

Alkene metathesis: It involves two stages first; the starting material in presence of catalyst forms two possible intermediates.  Next the intermediates react with the starting material and results to form product.
