Abstract

This work is a study of the product formed by the reaction of magnesium on bromobenzene in the absence of a solvent, and the results of hydrolysing this product.

  1. By refluxing bromo benzene and magnesium, reaction takes place to form phenylmagnesium bromide, di phenyl and terphenyl. The yield of phenyl magnesium bromide was found to be 24-30 %.
  2. The quantity of di phenyl formed is several times the runount formed when ether is used as a solvent. 3. Terphenyl was isolated from this reaction.
