PolyVinylPolyPyrrolidone-Supported Boron Trifluoride (PVPP-BF3); Highly Efficient Catalyst for Oxidation of Aldehydes to Carboxylic Acids and Esters by H2O2

Abstract

<em>A highly efficient method for the oxidation of aldehydes to carboxylic acids using PolyVinylPolyPyrrolidone supported - Boron Trifluoride (PVPP-BF₃) in the presence of 35% hydrogen peroxide has been developed in acetonitrile at 60 °C. This procedure cleanly oxidizes </em><em>variety of aldehydes </em><em>to the corresponding carboxylic acids. Oxidative esterification of benzaldehyde utilizing PVPP-BF₃/H₂O₂(35%) is also reported in good to excellent yields in acetonitrile at 60 °C.</em>
