Abstract:

If 1.5 equivalents of NF2CFO is allowed to react with a single equivalent of KF to form what is likely a mixture of KOCF2NF2 and KOCFNF22, this mixture may be thermally decomposed without explosion to yield perfluorourea. When KOCFNF22 is reacted with SiCl4, a new volatile compound, NF2CC1O is obtained. NF2CFO gives NF2CC1O with AlCl3. N,N- bistrifluoromethylhydroxylamine forms a solid adduct with either CsF or KF. The adduct will react at room temperature with perfluoroacyl and carbonyl halides to give the corresponding bistrifluoromethylnitroxo-compounds. Bistrifluoromethylketene is highly reactive with compounds that ordinarily add across olefinic double bonds, e.g., S2O6F2, N2F4, and NF2OSO2F. With the latter two, two isomers are obtained. Treatment with fluorine at -20C in the presence of CsF yields hypofluorites. A simple preparation of FNO was found which involves the reaction of nitrogen dioxide with KF or CsF. The conversion is about 48. This reaction may be carried out in metal or Pyrex glass vessels and the conversion rate is increased by heating.
