Abstract
Bismuthio methanides (C6H5)3Bi=C(SO2Rf)2 (R(f)=CF3, n-C4F9, OCH2CF2CF2 H) can be obtained as colourless solids from the sodium derivatives of the corresponding methanes with (C6H5)3BiCl2 in c. 90% yield. The com pounds have been characterized by NMR spectroscopy and elemental analy sis. From the NMR spectra, zwitterionic canonical structures containin g Bi+-C- or Bi+-C=S-O- units may be assumed.
