NEW HYPOFLUORITES CONTAINING NITROGEN
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 KOCF(NF2)2, this mixture may be thermally decomposed without explosion to yield perfluorourea. When KOCF(NF2)2 is reacted with SiCl4, a new volatile compound, NF2C(C1)O is obtained. NF2C(F)O gives NF2C(C1)O with AlCl3. N,N- bis(trifluoromethyl)hydroxylamine 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 bis(trifluoromethyl)nitroxo-compounds. Bis(trifluoromethyl)ketene 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.
