Direct Oxidation of Aldehydes to Methyl Esters with Urea Hydrogen Peroxide and p-Toluenesulfonyl Chloride
Combination of urea hydrogen peroxide and p-toluenesulfonyl chloride in methanol was proved to be facile and highly efficient for the oxidative methyl esterification of various aldehydes to the corresponding carboxylic methyl esters.

The oxidation of alcohols in the presence of methanol has been achieved using a ruthenium catalyst with crotononitrile as the hydrogen acceptor.
متن کاملFacile oxidation of aldehydes to acids and esters with Oxone.
[reaction: see text] A highly efficient, mild, and simple protocol is presented for the oxidation of aldehydes to carboxylic acids utilizing Oxone as the sole oxidant. Direct conversion of aldehydes in alcoholic solvents to their corresponding ester products is also reported. These reactions may prove to be valuable alternatives to traditional metal-mediated oxidations.
متن کاملGreen synthesis of nano polypyrrole using urea-hydrogen peroxide
Polypyrrole is one of the most useful conductive polymers, but green synthesis of this polymer has been restricted until now. The objective of the present paper is green synthesis of nano polypyrrole (PPy) by oxidative polymerization using urea-hydrogen peroxide. It was found that conductivity and morphology of polypyrrole are highly dependent on the reaction conditions such as the molar ratio ...
متن کاملPolyVinylPolyPyrrolidone-Supported Boron Trifluoride (PVPP-BF3); Highly Efficient Catalyst for Oxidation of Aldehydes to Carboxylic Acids and Esters by H2O2
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 variety of aldehydes to the corresponding carboxylic acids. Oxidative esterification of benzaldeh...
