Abstract

2-Alkyl-or 2-aryl-sulfinylpyridine N-oxides undergo ipso-substitution reaction with sodium ethoxide to afford sodium sulfenates which were converted soon to the corresponding sulfinates upon contact with oxygen. Sodium 2-pyridinesulfenate was prepared and characterized by FT-IR as the first example of stable sulfenate.
