Abstract

The convergent synthesis of 2-phenylethanol was executed with bromination of benzene in the presence of pyridine to give bromobenzene which was reacted with magnesium metal to give phenylmagnesium bromide. Ethene was generated from ethanol and converted to 1,2-dibromoethane which in turn was reacted with the Grignard in an inverse manner to give 2-phenylbromoethane. Reaction of 2-phenylbromoethane and aqueous sodium hydroxide, in acetone as solvent, yielded 2-phenylethanol.
 
      Key words: 2-Phenylethanol, 1,2-dibromoethane, 2-phenylbromoethane
