Abstract
The invention comprises perfluoroalkyl substituted amines of the formula ##STR1## wherein n is an integer from 1 to about 20, m is an integer between 2 or 4, R.sup.1 and R.sup.2 each is a hydrogen atom or a lower alkyl containing 1 to 3 carbon atoms and R.sup.3 and R.sup.4 each is a hydrogen atom, an alkyl containing 1 to 20 carbon atoms, an alkenyl containing 3 to 10 carbon atoms, a cycloparaffin radical containing 3 to 12 carbon atoms, a cycloalkenyl radical containing 5 to 12 carbon atoms, and N or O ring substituted cycloalkenyl radical containing 5 to 12 carbon atoms, or an aryl, or R.sup.3 or R.sup.4 are joined in the form of an alkylene radical of the formula EQU --(CHR).sub.p -- wherein p is an integer from 2 to 6 and R is a hydrogen atom or a lower alkyl containing 1 to 3 carbon atoms. These compounds are prepared by reacting at a temperature in the range between 0.degree. to 200.degree. C. perfluoroalkyl halides of the formula EQU C.sub.n F.sub.2n+1 (CR.sup.1 R.sup.2).sub.m Y (II) wherein n, m, R.sup.1 and R.sup.2 each has the same meaning as defined hereinabove and Y is an iodine or a bromine atom with amines of the formula ##STR2## wherein R.sup.3 and R.sup.4 have the s…
