Nitrogen difluoride radical

Oxygen Difluoride as a Source of the OF Radical. The existence of the OF radical [12061 -70-0] was first reported in 1934 (27). This work was later refuted (28). The OF radical was produced by photolysis of OF2 in a nitrogen or argon matrix at 4 K. The existence of the OF species was deduced from a study of the kinetics of decomposition of OF2 and the kinetics of the photochemical reaction (25,26) ... 

The following isomers are represented 2H, 4H and 3H, 4H. A benzo-1,2-thiazete 447 has been proposed as an intermediate in the reaction of phenyl nitrene (triplet) with the thiazo derivative 446 a sulfurane structure 448 was suggested for one product of the reaction of perfluoropropyliminosulfur difluoride with per-fluoropropene. Stable benzo- and naphthyl-l,2-thiazetyl radicals (e.g., 452) are obtained by thermolysis of 5-amino compounds 449, 450, and 451. Electron-spin resonance studies established the structures. The magnitude of the spin density on nitrogen in derivatives of 452, which carry a substituent para to the nitrogen atom, depends on the nature of the substituent. Loss of sulfur from the naphthyl derivative 453 occurs at temperatures above 150°C. ... 

Methane forms explosive mixtures with air the LEL and UEL values are 5.5% and 14% by volume of air, respectively. The explosion is loudest at 10% volume concentration. The combustion of methane in air forming CO2 involves chain reactions, propagated by free radicals, CH3-, HO-, H-, and O- (Meyer 1989). Being a saturated molecule, the reactivity of methane toward most substances is very low. However, under catalytic conditions, violent reactions have been reported with halogens and certain fluorides of nonmetals. This includes reactions with chlorine at room temperature over yellow mercuric oxide, bromine pentafluoride, oxygen difluoride in the presence of a spark (MeUor 1946, Suppl. 1956), and nitrogen trifluoride (Lawless and Smith 1968).
