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

A considerably improved method for the Cu-catalyzed coupling of sulfurylchloride with P(O)–H was described. Using commercially available l-proline as the ligand decreased the precatalyst loading, broadened the substrate scope and greatly promoted the efficiency of the coupling reaction. Moreover, gram-scale preparation, easy-to handle and recyclable catalyst featured this transformation.

O,O-Dialkyl-S-aryl-phosphorothioates are thermally unstable and decompose readily at a temperature of about 150° with formation of alkyl aryl sulfides and polymeric alkyl meta- or -polyphosphates. Differences in reactivity within a series of 33 phosphorothioates are rationalized on the basis of steric and electromeric effects. The mechanism of the thermal degradation is discussed, the influence of

The improved procedure for the synthesis of S-arylphosphorothioates from dialkyl phosphites (H-phosphonates), aryl iodides and elemental sulfur deals with the application of rongalite (sodium hydroxy-methanesulfinate) as the radical promoter. The reactions proceeded smoothly to give S-arylphosphorothioates in good yields.
