Low-temperature fluorination of N,N-dichloro-1-fluoroformamide, FC(O)NCl2, has provided a more convenient, high-yield (75percent) synthesis of dichlorofluoramine, FNCl2, than was previously available.In an attempt to further expand the novel metal fluoride promted conversion of N-Cl bonds to N-Br bonds, both FC(O)NCl2 and FNCl2 were reacted with bromine in the presence of various alkali metal fluorides.No evidence was found for the formation of either FC(O)NBrCl and FC(O)NBr2 or FNBrCl and FNBr2 in these reactions.In fact, FC(O)NCl2 was found to decompose to C(O)F2, N2, and Cl2 in the presence of alkal metal fluorides.
