New aspect of methanesulfonyl chloride: Unusual deoxygenations of pyridine N-oxides with methanesulfonyl chloride and triethylamine

Article abstract of DOI:10.1246/cl.1998.829

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.
