Chapter 9.SE, Problem 44AP

Interpretation Introduction

Interpretation:

Starting from acetylene and using any alkyl halide required how cyclodecyne can be prepared is to be shown.

Concept introduction:

An open chain alkyne can be converted in to a cyclic alkyne with more number of carbons, first by converting it in to a disodio derivative by treatment with two molar equivalents of NaNH₂ in NH₃ followed by treatment with a suitable dibromide containing the required number of carbons.

To show:

Starting from acetylene and using any alkyl halide required how cyclodecyne can be prepared.
