Abstract
The charge distribution in the polyfluoroaromatic N,N-dichloroamides and -amines and their hydrocarbon analogues has been established from the X-ray fluorescent ClKα- and SKα-spectra and X-ray photoelectron spectra of chlorine, sulphur and nitrogen in comparoson with data obtained from NQR 35Cl frequencies and semiempirical calculations by CNDO/2. The action of sulphur and selenium on the N,N-dichloroamides of pentafluorobenzenesulphonic acid and pentafluorobenzoic acid leads to the corresponding S,S-dichlorosulphimines and Se,Se-dichloroselenoimines respectively. The polyfluoroaromatic N,N-dichloroamimes have been found to form polyfluorinated trans-azobenzenes under the same conditions. The mechanism of these reactions has been discussed.
