Novel One-step Preparation of Sulfinic Acid Derivatives from Sulfinic Acid

抄録

Convenient one-step syntheses of sulfinamides and sulfinate esters from sulfinic acids were achieved by using coupling reagents, such as 2-chloro-1-methylpyridinium iodide, γ-saccharine chloride, N, N'-dicyclohexylcarbodiimide, and diethyl azodicarboxylate and triphenylphosphine. Ammonolysis of sulfinate esters also gave sulfinamides.
