Potassium carbonate as a green catalyst for Markovnikov addition of azoles to vinyl acetate in PEG

Abstract

A novel strategy to effect the Markovnikov addition between azoles and vinyl-acetate is described. The main attractive features of this process are a mild base catalyst, recyclability of solvent PEG, excellent yields of products, and easy workup procedure.

Keywords:

• Markovnikov addition
• K₂CO₃
• PEG
• N-heterocycles
• recyclability
