Abstract
The invention relates to polyfluoroalkyl nitrogen compounds of general formula: R.sub.F --(CH.sub.2).sub.2 --X in which X denotes an isothiocynate --N.dbd.C.dbd.S, carbodiimide --N.dbd.C.dbd.N(CH.sub.2).sub.2 --R'.sub.F or thiourea --NH--CS--A group, A denoting an optionally substituted amino group, and each of the symbols R.sub.F and R'.sub.F denotes a perfluoroalkyl radical. These compounds, prepared from the corresponding azides R.sub.F (CH.sub.2).sub.2 N.sub.3 or amines R.sub.F (CH.sub.2).sub.2 NH.sub.2, can be used as surface-active agents or precursors of such agents.
