Sodium tungstate-catalyzed 'on-water' synthesis of β-arylvinyl bromides

摘要

Synthesis of structurally varied β-arylvinyl bromides has been accomplished in an eco-friendly "On-water" condition through bromodecarboxylation reaction of appropriately substituted cinnamic acids with potassium bromide using hydrogen peroxide as oxidant and sodium tungstate as catalyst.Salient mechanistic features have also been highlighted.
