Magnetically recyclable Cu-BTC@Fe<sub>3</sub>O<sub>4</sub> composite-catalyzed C<sub>(aryl)</sub>–S–P bond formation using aniline, P(O)H compounds and sulfur powder
Cu-BTC@Fe3O4 composite was prepared and exhibited good catalytic activity toward the synthesis of S-aryl phosphorothioates. This three-component reaction involved the coupling of in situ generated aryl diazonium salts from aniline, R2P(O)H, and sulfur powder, allowing the facile and direct formation of C(aryl)-S-P bonds. A broad scope of substrates survived the reaction conditions to afford the corresponding

disulfides has been developed under mild reaction conditions. In addition, an aerobic oxidative cross-dehydrogenativecoupling (CDC) reaction of thiols with P(O)–H compounds (H-phosphonates and H-phosphine oxide) for the formation of S–P(O) bonds has been demonstrated under the Fe(Pc) catalysis system with a base additive. Control experiments revealed that the use of a base (DIPA) in this system controls

The synthesis method of P(O)-S organophosphorus compounds by dehydrogenative coupling reaction of P(O)H compounds and aryl thiols was developed. The reaction was carried in the presence of a base and air, and exhibited good characters such as metal-free, mild reaction temperature, excellent substrate tolerance and with moderate to good yields. A plausible mechanism was proposed.
