Electrochemical Dehydrogenative Phosphorylation of Thiols

We report herein a new approach for the synthesis of organothiophosphates from phosphonates and thiols through electrochemical reaction. The reactions were conducted without the addition of oxidant, transition-metal base, or base at room temperature. This

Fast and transition metal-free general method for the preparation of chalcogenophosphates

In the presence of Cs2CO3 and I2, the coupling reaction of dialkyl phosphites with dichalcogenides (S, Se and Te) proceeds efficiently and completes in several minutes under mild conditions, affording the corresponding cha

Iodine-catalyzed sulfenylation of H-phosphonates with diaryl disulfides under metal, base and solvent-free conditions

Background: Although the exploitation of facile and efficient preparation for S-aryl phosphorothioates has gained considerable interest, there is still great demand for the development of a direct, convenient and especially environmentally benign protocol

Peroxide promoted metal-free thiolation of phosphites by thiophenols/disulfides

A metal-free oxidative P-S bonds coupling method for the synthesis of thiophosphates with DTBP as the oxidant is established. A wide range of functionalities are tolerated in the method. This method provides a facile way to synthesize thiophophates from readily available thiophenols/disulfides and phosphites.

N-Chlorosuccinimide-promoted synthesis of thiophosphates from thiols and phosphonates under mild conditions

A very simple N-chlorosuccinimide-promoted synthesis of thiophosphates through the coupling of thiols and phosphonates is reported. Notably, the reactions were carried out in the absence of a base. Functional groups including fluoro, bromo and trifluoromethyl are all tolerated by the reaction conditions employed. Both aryl and alkyl thiols are coupled smoothly with a broad spectrum of phosphonates to afford the corresponding thiophosphates in good to excellent yields.

A simple and convenient method for the synthesis of S-aryl phosphorothioates catalyzed by cesium hydroxide

In the presence of a catalytic amount of cesium hydroxide, the corresponding S-aryl phosphorothioates can be obtained by the reactions of dialkyl phosphites with diaryldisulfides in excellent yields at room temperature, using DMSO as a solvent. The reaction mechanism was discussed. The method provides a new and expedient path for the preparation of S-aryl phosphorothioates.

A novel and general method for the formation of S-aryl, Se-aryl, and Te-aryl phosphorochalcogenoates

A new and general method for the synthesis of S-, Se-, and Te-aryl phosphorochalcogenoates (chalcogenophosphates) has been developed. S-P, Se-P, and Te-P bonds were formed by the coupling of readily available dialkyl phosphites with diaryl dichalcogenides at 30°C in dimethyl sulfoxide in the presence of catalytic amounts of copper iodide and diethylamine. The reaction proceeded smoothly without exclusion of moisture or air. Georg Thieme Verlag Stuttgart.

Free radical reaction of dialkyl phosphites and organic dichalcogenides: A new facile and convenient preparation of arylselenophosphates

Azobisisobutyronitrile-initiated free radical reaction of dialkyl phosphites with diaryl diselenides afforded arylselenophosphates in high yields. Arylthiophosphates and aryltellurophosphates can also be synthesized by similar reaction of diaryl disulfide
