Oxidation Using Quaternary Ammonium Polyhalides. III. An Effective Oxidation of Alcohols and Ethers by the Use of Benzyltrimethylammonium Tribromide

Article abstract of DOI:10.1246/bcsj.62.2585

The reaction of primary alcohols or simple ethers and α,ω-diols or cyclic ethers with a stoichiometric amount of benzyltrimethylammonium tribromide (BTMA) Br3) in carbon tetrachloride in the presence of Na2HPO4 aq or in acetic acid in the presence of CH3CO2Na aq at 60-70 deg C gave dimeric esters and lactones respectively in good yields.The reaction of secondary alcohols with 1 equiv of BTMA Br3 in the presence of a buffer at 60 deg C gave ketones.
