An Efficient Synthesis of N-Bromoperhalo-1-alkanimines

Article abstract of DOI:10.1021/jo00182a040

Certain perhalogenated nitriles have been found to react readily with bromine and active cesium fluoride to afford high yields of N-bromoperhalo-1-alkanimines (R_xFC=NBr; R_x = CF3, C2F5, n-C3F7, CF2Cl, CCl3).Photolysis of the perfluorinated N-bromo compounds affords the novel perfluoroazines R_fFC=NN=CFR_f.
