Interpretation Introduction

(b)

Interpretation:

The two reaction sequences for reaction of conversion of 1-bromo-1-methylcyclohexane into methylcyclohexane by the use reagents other than of tributyltin hydride (Bu3Sn−H) are to be predicted.

Concept introduction:

Grignard reagents are organometallic compounds which are prepared using alkyl halides in presence of magnesium metal in dry ether. These reagents act as strong nucleophiles and bases.

Alkyl halides undergo elimination reaction in the presence of a base to form alkenes. The mechanism of the reaction followed depends on the base used.
