Description

The synthetic method of bis-(ο-trifluoromethylphenyl) dithiophosphinic acid has been improved during the synthetic research of various dithiophosphinic acids. The optimized synthesis has been realized with PCl3 and (ο-F3CC6H4) MgBr as starting materials and via a continuous three-step method including Grignard reaction, sulfuration and substitution reaction. The FTIR spectrum of product shows the presence of substituted aromatic ring, C-F bond, P-S single bond and P=S double bond. The interpretation result f 31P NMR, 1H NMR and 13C NMR of the product, as well as MS, is completely in line with the structure of the targeted compound bis-(ο-trifluoromethylphenyl) dithiophosphinic acid.
