Verfahren zur Herstellung von neuen tertiären Aminen
In der österr. Patentschrift Nr. 191869 ist ein Verfahren zur Herstellung von tertiären Aminen der allgemeinen Formel I :
EMI1.1
beschrieben, nach welcher man tertiäre Aralkylaminonitrile der Formel H :
EMI1.2
mit Organomagnesiumhalogeniden der Formel III:
Y-Mg-Hal (III) in Gegenwart von Lösungsmitteln umsetzt.
Hiebei bedeuten Ri und Rz eine Alkyl-, Oxyalkyl-, Cycloalkyl-, Aryl- oder Aralkylgruppe, wobei R und R2 gleich oder verschieden sein oder auch mit N einen gegebenenfalls ein weiteres Heteroatom enthaltenden heterocyclischen Ring bilden können, und R Wasserstoff, eine Alkyl-oder Alkoxygruppe und Y einen gegebenenfalls substituierten Aryl-, Alkyl-, Aralkyl- oder Cycloalkylrest. wobei R kein Wasserstoffatom sein kann, wenn Y Phenyl oder ein Alkylrest mit 1-2 Kohlenstoffatomen ist.
Es wurde nun gefunden, dass man die neuen l- (Halogenphenyl)-2-aminoalkane der allgemeinen Formel IV :
EMI1.3
EMI1.4
<Desc/Clms Page number 2>
- N ()verzweigten Alkylrest bedeuten, erhält, wenn man 1, 4-Dihalogenbutan bzw. l, 5-Dihalogenpentan auf primäre Amine der allgemeinen Formel V :.

Process for the preparation of new tertiary amines
In the Austrian patent specification No. 191869 a process for the preparation of tertiary amines of the general formula I is:
EMI1.1
described, according to which tertiary aralkylaminonitriles of the formula H:
EMI1.2
with organomagnesium halides of the formula III:
Y-Mg-Hal (III) in the presence of solvents.
Here, Ri and Rz denote an alkyl, oxyalkyl, cycloalkyl, aryl or aralkyl group, where R and R2 can be identical or different or can also form a heterocyclic ring with N, which may optionally contain another heteroatom, and R is hydrogen, an alkyl or alkoxy group and Y is an optionally substituted aryl, alkyl, aralkyl or cycloalkyl radical. where R cannot be a hydrogen atom when Y is phenyl or an alkyl radical having 1-2 carbon atoms.
It has now been found that the new 1- (halophenyl) -2-aminoalkanes of the general formula IV:
EMI1.3
EMI1.4
<Desc / Clms Page number 2>
- N () denote branched alkyl radical, obtained when 1, 4-dihalobutane or l, 5-dihalopentane on primary amines of general formula V:
EMI2.1
EMI2.2
