A highly efficient and environmentally-friendly base-mediated transition metal-free direct thiophlic catalytic approach has been reported for the synthesis of S-benzhydryl-phosphorothioates by reacting phosphite nucleophiles with diarylmethanethione. A wide variety of thioketones were coupled with different phosphite derivatives to provide the corresponding phosphorothioates in good to excellent yields. The control experiments, and density functional theory (DFT) calculations relies on the regio-selective thiophilic addition of phosphite nucleophile via umpolung protocols.
