When bis(o-trifluoromethylphenyl)dithiophosphinic acid (1) is dissolved in methanol, crystals of bis(o-trifluoromethylphenyl)dithiophosphinic methyl ester (2) are formed. The structure of dithiophosphinic methyl ester (2) has been characterized 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. The transformation to 2 suggests that the o-trifluoromethylphenyl groups on phosphorus assist in retaining the PS2 core, possibly by steric hindrance.
Graphical abstractCrystals of bis(o-trifluoromethylphenyl)dithiophosphinic methyl ester were isolated, and the structure of dithiophosphinic methyl ester was determined by single-crystal X-ray diffraction and multinuclear NMR studies. This compound is remarkable in that the dithiophosphinic (PS2) core is preserved during this transformation. The results suggest that the compound is stable during this transformation, possibly due to the sterically encumbering o-trifluoromethyl groups.Figure optionsDownload full-size imageDownload as PowerPoint slideResearch highlights► Unique aromatic dithiophosphinic methyl ester is isolated. ► Dithiophosphinic methyl ester is determined by X-ray and multinuclear NMR. ► Dithiophosphinic (PS2) core is preserved during this transformation. ► o-Trifluoromethylphenyl groups might assist in the transformation.
