Mild Oxidative Bromination of Alkenes and Alkynes with Zinc Bromide and Lead Tetraacetate

Abstract

Zinc bromide and lead tetraacetate is a practical and safe source of bromine. The combined reagents are used to brominate a variety of alkenes to vicinal dibromoalkanes. Similarly, alkynes can be converted into dibromoalkenes in high yields. The reagents are also capable of tetrabromination of alkynes.
