- 中文摘要: The ethylenebis(N-methylimidazolium) chlorochromate was prepared by addition of N-methylimidazole to 1,2-dibromoethane to form the corresponding dibromide salt and subsequent treatment of this salt with CrO3 in 6N HCl solution. It is a stable yellow-orange solid which selectively oxidized benzylic and allylic alcohols, hydroquinones and trimethylsilyl ethers in refluxing acetonitrile. Oxidation of alcohols was also examined under solvent-free conditions and showed much better yields of the corresponding carbonyls in a very short reaction time when compared with the conventional method.
