Its distinctive deep blue colour is unusual for a gas. HistoryTrifluoronitrosomethane was synthesized for the first time in 1936 by Otto Ruff and Manfred Giese at the University of Wrocław.[1] It was created through the fluorination of silver cyanide in the presence of silver nitrate and silver oxide. ProductionTrifluoronitrosomethane can be produced from the reaction of trifluoroiodomethane and nitric oxide under a UV light with a yield of up to 90% in normal pressure. A small amount of mercury is needed as catalyst. The reaction results in the creation of iodine as a by-product.[2][3][4] PropertiesTrifluoronitrosoethylene is also a deep blue gas.[5] Although it is somewhat more kinetically stable due to its fluorine substituents, trifluoronitrosomethane, like other nitroso compounds, has a weak C–N bond of only 39.9 kcal/mol.[6] References1. ^O.
