Abstract: | Pentafluorophenyl Compounds of Phosphorus The preparation of compounds of the type R(C6F5)PX (R = CH3, C2H5, t-C4H9 and C6H5: X = F, Cl, Br and N(C2H5)2) is described. These derivatives are converted to trifluorophosphoranes, R(C6F5)PF3, and phosphinic acid fluorides, R(C6H5)P(:O)F. The n.m.r. spectra are discussed. |
