Fluorination of azidotrifluoromethane furnishes difluoramino trifluoromethane in a direct, reproducible, and high yield reaction.A maximum rate of conversion with minimum degradation was obtained at 70-80 deg.Enhancement of the rate of reaction was realized with added KF as a catalyst.
On the reaction of perfluoro-aza-propene with oxygen difluoride and fluorination of bis(trifluoromethyl)-hydroxylamine
The reactions of perfluoro-aza-propene CF3NCF2 with an excess of oxygen difluoride OF2 and the fluorination of bis(trifluoromethyl)-hydroxylamine (CF3)2NOH are discussed. Additionally, we present density functional calculations (B3LYP/6-31G*) on bis(trifluoromethyl)-hypofluorite (CF3)2NOF, which clearly show that this molecule is a model substance for the discussion of negative hyperconjugation.
