Abstract: | Preparation of N-Methylhalidonitrilium Salts XCNCH3+MF6? (X = Cl, Br, I; M = As, Sb) and the N-Methyl-trifluoroacetonitrilium Salts CF3CNCH3+MF6? The N-methyl-halidonitrilium salts XCNCH3+MF6? (X = Cl, Br, I; M = As, Sb) are synthesized by methylation of cyanogen halides with CH3F/MF5 in SO2 at low temperatures. The N-methyl-trifluoroacetonitrilium salts CF3CNCH3+MF6? (M = As, Sb) are formed analogous with trifluoroacetonitrile. All salts are characterized by vibrational and NMR spectroscopy. |
