A robust methodology for the synthesis of phosphorothioates, phosphinothioates and phosphonothioates, including those bearing low molecular weight S-alkyl side-chains, is presented. Application of the “caesium effect” in conjunction with the disulfide 3,3’-dithiobis(propionitrile), which acts as a shelf-stable sulfur source, avoids recourse to malodorous alkanethiols and toxic P?Cl precursors. A diverse range of sulfur-containing organophosphorus targets, including phosphorus-based heterocycles, may be prepared in consistently high yields. This chemistry also provides ready access to the corresponding DBU salts which are potential substrates for Pd-catalysed coupling reactions. (Figure presented.).

An efficient Cs2CO3-catalyzed oxidative coupling of thiols with phosphonates and arenes that uses molecular oxygen as the oxidant is described. These reactions provide not only a novel alkali metal salt catalyzed aerobic oxidation, but also an efficient approach to thiophosphates and sulfenylarenes, which are ubiquitously found in pharmaceuticals and pesticides. The reaction proceeds under simple and mild reaction conditions, tolerates a wide range of functional groups, and is applicable to the late-stage synthesis and modification of bioactive molecules.
