Synthesis of phosphorothiolates

Recent Literature


The use of the iminium salt prepared from N,N-dimethylthioformamide and Meerwein’s salt enables a direct and rapid conversion of primary and secondary alcohols to the corresponding phosphorothiolates in good yields. Selective reaction of primary alcohols in the presence of secondary alcohols is possible. The reaction of secondary alcohols proceeds stereospecifically with inversion of configuration.

A multicomponent reaction involving aryl boronic acids, elemental sulfur, and P(O)H compounds provides valuable S-aryl phosphorothioates and S-aryl phosphorodithioates in excellent yields. Moreover, this method can be easily scaled up.

Green methods based on copper-catalyzed multicomponent reactions enable the synthesis of S-aryl phosphorothioates from diaryliodonium/arenediazonium salts, elemental sulfur, and R2P(O)H compounds in very good yields at room temperature. These transformations allow the direct formation of P-S and C-S bonds in one reaction.
