NHC-Catalyzed Metathesis and Phosphorylation Reactions of Disulfides: Development and Mechanistic Insights

The development of efficient methods for the metathesis and phosphorylation reactions of disulfide compounds is of widespread interest due to their important synthetic utility in polymer, biological, medicinal and agricultural chemistry. Herein, we demonstrate the use of N-heterocyclic carbenes (NHCs) as versatile organocatalysts to promote these challenging reactions under mild conditions. This metal- and oxidant-free protocol is operationally simple with very short reaction times. The interplay between the nucleophilicity and basicity of NHCs in these reactions were also elucidated by NMR studies and high-level ab initio calculations.

Synthesis of Thiophosphates by Coupling of Phosphates with Bunte Salts under Mild Conditions

A simple, green, and efficient method has been developed for the preparation of thiophosphates with sodium S-benzyl thiosulfates. The method uses an NaBr-catalyzed coupling reaction of Bunte salts with phosphonates in the presence of an acid and hydrogen peroxide (30%), and the desired products were obtained in good yields.

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.
