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

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.

We report in this work an environmentally benign zinc mediated synthesis of aryl and benzyl phosphorochalcogenoates in ethanol within a short reaction time. In vitro antimicrobial study along with statistical analysis and seed germination assay were performed. These chalcogenophosphates possess strong antimicrobial activity against the reference strains. The antibacterial activity was determined against four standard strains (Bacilus subtilis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa). The antifungal activity was evaluated against one fungal strain Candida albicans. (C) 2014 Elsevier Ltd. All rights reserved.
Synthesis of <i>S</i>-Aryl Phosphorothioates by Copper-Catalyzed Phosphorothiolation of Diaryliodonium and Arenediazonium Salts
Green methods for the synthesis of S-arylphosphorothioates have been developed based on copper catalyzed multicomponent reactions involving diaryliodonium/arenediazoniumsalts, elemental sulfur, and P(O)H compounds. Most target products are obtained with these two methods in good to high yields at room temperature. These transformations allow the direct formation P-S and C-S bonds in one reaction.
