The syntheses of a large number of stable compounds which contain difluoroaminoxy ONF2 difluoroamino NF2, nitroso NO, nitro NO2, azo -NN-, fluorimino NF, andor dichloroamino NCI2 groups have been accomplished successfully. The mechanisms for their formation have been elucidated and their reaction chemistries studied extensively. In many cases their structures have been determined through the use of electron diffraction or X-ray crystallographic techniques. It has been found that NF2O is a powerful precursor for NF2O-containing compounds as well as for the in situ preparation of FNO when reacted with NO. Fluorination of NOC1 or NO2 with potassium fluoride also provides a ready source of FNO which has served as a useful precursor for a number of F-nitroso compounds whose chemistry has been pursued additionally. Tetrafluorohydrazine with polyfluoroolefins provided intermediates which led to new families of mono and bis dichloroamines that could be converted easily to highly fluorinated diazines. Kewords Carbonyl fluoride, fluorinating agents, trifluoroamine oxide, N,N-difluorohydroxylamino group, nitrosyl fluoride, hepta-fluoronitrosocyclobutane, fluoroamines.
