A solventless mechanochemical methodology for the oxidation of electron-poor fluorinated anilines to the corresponding symmetrical azo compounds has been developed. In this process phenyliodine(III)diacetate and inexpensive calcium hypochlorite demonstrat

Fluorine-containing N-arylhydroxylamines have been obtained by the reaction of hydroxylamine or its N- and O-derivatives on polyfluorinated benzenes and pentafluoropyridine.The influence of fluorine atoms on the reactivity of hydroxylamino group has been investigated.The reaction of N-polyflouroarylhydroxylamines with aldehydes has been shown not to occur, whereas their reaction with nitrosobenzenes leads to azoxybenzenes and with Lewis acids leads to corresponding nitrosobenzenes, azoxybenzenes and anilines.The action of acids on 2,3,5,6-tetrafluorophenylhydroxylamine leads to the acid-catalyzed rearrangement of the latter into 4-amino-2,3,5,6-tetrafluorophenol.C,N-Diarylnitrones have been obtained by the oxidation with MnO2 of fluorine-containing arylhydroxylamines possessing the CH-fragment in an α-position.

In the reaction of the N,N-dichloroamides of pentafluorobenzenesulfonic and pentafluorobenzoic acids with sulfur and selenium the corresponding iminosulfur and iminoselenium dichlorides are formed.It was found that polyfluorinated azobenzenes are formed in the reaction of N,N-dichloroamines of the polyfluorinated aromatic series with sulfur and selenium.The charges at the chlorine atoms of polyfluorinated aromatic N,N-dichloroamides and N,N-dichloroamines were determined on the basis of data from 35Cl NQR, the x-ray fluoroscence mechanism spectra of the chlorine, and quantum-chemical calculations by the CNDO/2 method.The mechanism of the reactions of polyfluorinated aromatic N,N-dichloroamides and N,N-dichloroamines with sulfur and selenium is discussed.

The behaviour of 4-XC6F4NH2 (X=NO2, CN, F, H, CH3, OCH3, C4H9) in reaction with tert-butyl hypochlorite was investigated.Polyfluorinated anilines containing electron-donating substituents form N-chloroiminopolyfluorochloro-2,5-cyclohexadienes, whereas the
