New Aspect of Methanesulfonyl Chloride: Unusual Deoxygenations of Pyridine N-Oxides with methanesulfonyl Chloride and Triethylamine

Abstract

Abstract Treatment of several pyridine N-oxides with an excess of methanesulfonyl chloride and triethylamine brought about a deoxygenation reaction to give efficiently the corresponding reduction products without chlorination of the pyridine nucleus.
