Magnetic nanoparticles of CuFe2O4 were applied as catalyst system for one-pot thiophosphate synthesis via the reaction of aryl sulfonyl chlorides with H-phosphonates under conventional heating conditions. This is an extremely efficient and green method for thiophosphate synthesis under base- and solvent-free conditions. Various thiophosphates were obtained in good to excellent yields under the optimized reaction conditions in a short time. The catalyst can be easily recycled from the reaction by an external magnetic field and reused for the next run. In this study, TD-DFT B3LYP/6-31 + G(d) calculations are in good accord with the experimental results. A comparison between experimental and theoretical UV-vis absorption spectra of the thiophosphate 3k has been carried out; and a small hypsochromic shift (only ~ 2 nm) was displayed at maximum absorption. The aim of this work is to investigate the best method and basis set for thiophosphate compounds; therefore, predictions for these compounds can be performed in theoretical studies.

An efficient procedure for the synthesis of thiophosphates is described. Without using any metallic catalyst or base, the direct sulfur–phosphorus coupling reaction of disulfides and dialkyl trimethylsilyl phosphite (DTSP) was carried out under solvent-fr
