Ipso-substitution reaction of 2-sulfonylpyridines and their N-oxides with alkoxide or thiolate anion afforded the sodium salts of sulfinic acids together with the corresponding substitution products in high yields. This procedure becomes a convenient and versatile method for preparation of various sulfinic acids.
