In this manuscript we describe the oxidative fluorination of aryl phosphorothiolates to access Ar-SF4Cl compounds. These compounds serve as precursors for the highly coveted Ar-SF5 compounds. The use of phosphorothiolates as starting materials permits access to Ar-SF4Cl from a wide variety of available starting materials, namely boronic acids, diazonium salts, aryl iodides, thiophenols, or simple arenes. The protocol has been demonstrated for 10 examples and showed good tolerance to various functional groups. Finally, we demonstrated that AgBF4 can be used as a fluorinating agent, affording good yields of an Ar-SF5.

A Tf2O/DMSO-based system for the dehydrogenative coupling of a wide range of alcohols, phenols, thiols, and thiophenols with diverse phosphorus reagents has been developed. This metal- and strong-oxidant-free strategy provides a facile approach to a great variety of organophosphinates and thiophosphates. The simple reaction system, good functional-group tolerance, and broad substrate scope enable the application of this method to the modification of natural products and the direct synthesis of bioactive molecules and flame retardants.

The invention discloses a synthetic method of a phosphorothioate compound. The preparation method comprises the following steps: with thiol as a reaction substrate and trichloroisocyanuric acid (TCCA)as an accelerant, reacting the reaction substrate and the accelerant in an organic solvent at normal temperature and normal pressure for 10-20 minutes, then adding phosphite triester, continuing reacting for 10-20 minutes, and after the reaction is finished, carrying out separation treatment to obtain the phosphorothioate compound. According to the synthesis method disclosed by the invention, thereaction is carried out at normal temperature and normal pressure without special requirements; reaction time is short; and reaction substrate universality is good.
