A promoter-free chalcogenophosphorylation reaction between diverse P(O)À H reagents and chalcogenosulfonates has been developed. In the absence of metal or any other additives, these transformations proceed through a spontaneous process at room temperature, which provide a convenient and compatible approach to a broad range of selenophosphates and thiophosphates.

A metal-free method for the dual activation of aryl phosphinate has been developed; the P-H and P-O bonds are sequentially activated by the Tf2O/DMSO system. Without the requirement of metals...

A novel strategy of bisphosphorylation of anhydride with P(O)−H reagents via a DMAP-catalyzed and a DBU-promoted processes have been developed. These one-step transformations proceed efficiently to provide convenient access to...
