General description

Sodium methanesulfinate is an aliphatic sodium sulfinate. Conjugate addition of sodium methanesulfinate to vinyl heterocycles has been described. Cross-coupling reaction between aryl boronic acid and sodium methanesulfinate has been studied. Its stock solution was prepared from methanesulfonic acid by adding one equivalent of sodium hydroxide and diluting it to 4M.
