摘要:
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 (PS(2)) core is preserved during this transformation. The transformation to 2 suggests that the o-trifluoromethylphenyl groups on phosphorus assist in retaining the PS(2) core, possibly by steric hindrance. Published by Elsevier B. V.
