CCl4-Induced Synthesis of Phosphonothioates, Sulfoxides, and Sulfones from Sodium Sulfinates

An external reductant-free and acid-free synthesis of phosphonothioates from odorless sodium sulfinates induced by CCl4 (1.0 equiv) under mild conditions has been achieved. This transformation provides an efficient synthetic approach to phosphonothioates in up to 98% yield with good functional group compatibility. In addition, an unexpected CCl4-induced synthesis of sulfoxides and sulfones from sodium sulfinates using DMSO as the solvent has been developed.
