Synthesis of S-Sulfonyl-Phosphinothioates and Phosphinodithioates, a Novel Organophosphorus-sulphur Structure

Abstract

Racemic and optically active S-sulphonylphosphinothioates R-SO₂-S-P(O)Bu'Ph and dithioates R-SO₂-S-P(S)Bu'Ph (R [dbnd] Me, p-tolyl) have been prepared for the first time by the reaction of the corresponding acids Bu'PhP(S)SH (X [dbnd] O,S) of their salts with sulphonylating reagents RSO₂-Y (Y [dbnd] Cl, O-SO₂R, triazolide).
