PREPARATION, NMR-SPECTROSCOPY AND REACTIV ITY OF PERFLUOROALKYLSILVER(I) COMPOUNDS

Perfluoroalkylsilver(I) compounds are obtained via ligand exchange rea ctions of AgNO3 and Cd(R-f)(2) compounds in aprotic polar solvents. Eq uilibria between the neutral species AgRf . D and the ionic species [A g(R-f)(2)](-) involve silver(I) ions and exhibit strange solvent-depen dency. The F-19- and Ag-109-NMR data as well as the T-1-values have be en measured. Reactions with e.g. C6H5HgCl proceed at -30 degrees C wit hin a few minutes to give the corresponding phenyl(perfluoroalkyl)merc ury derivatives. However, the versatility of AgR,reagents as perfluoro alkyl-group transfer reagents in DMF and N(C2H5)(3) remains limited.
