Chapter 17.SE, Problem 70AP

Interpretation Introduction

Interpretation:

Using cyclohexanone as the only source of carbon a method for synthesizing biscyclohexylidene is to be proposed.

Concept introduction:

Cyclohexanone can be converted in to a Grignard reagent first by reduction with LiAlH₄, then treating with PBr₃ followed by treating with Mg. Treatment of Grignard reagent with another molecule of cyclohexanone will yield a tertiary alcohol which on dehydration with H₂SO₄ yields the product desired.

To propose:

A method to synthesis biscyclohexylidene using cyclohexanone as the only source of carbon.
