Chapter 9.SE, Problem 45AP

Interpretation Introduction

Interpretation:

Starting from acetylene and using any alkyl halide needed how muscalure, the sex attractant given off by house fly, can be prepared is to be shown.

Concept introduction:

By converting alkynes in to alkynides by treating with NaNH₂ in NH₃ and treating the acetylide with alkyl halides having the required number of carbons a higher alkyne can be prepared. The higher alkyne thus obtained upon reduction with H₂ in the presence of Lindlar catalyst yields a cis alkene as the product.

To show:

Starting from acetylene and using any alkyl halide needed how muscalure, the sex attractant given off by house fly, can be prepared.
