When bis(o-trifluoromethylphenyl)dithiophosphinic acid (1) was dissolved in methanol, crystals of bis(o-trifluoromethylphenyl)dithiophosphinic methyl ester (2) were isolated. The structure of dithiophosphinic methyl ester (2) has been identified via single-crystal X-ray diffraction and multinuclear NMR studies. Compound 2 is remarkable in that the dithiophosphinic (PS2) core is preserved during this transformation. Many dithiophosphinic acids degrade to other compounds over time which results in formation of dithiophosphinic dimers, like the bis(dithiophosphinic) anhydride. The transformation to 2 suggests that the o-trifluoromethylphenyl groups on phosphorus assist in retaining the PS2 core, possibly by steric hindrance.
