The preparation of compounds which contain one or more groups of the general formula (I) DOLLAR A -CH¶2¶-CH (NR.1 · R · 2 ·) - DOLLAR A with R · 1 ·, R · 2 · independently from each other hydrogen, C¶1-20¶-alkyl, C¶6-18¶-aryl, C¶7-20¶-alkaryl, C¶7-20¶-aralkyl or polyamine residue DOLLAR A takes place by reductive amination of compounds which contain one or more groups of the general formula (II), DOLLAR A -CH¶2¶-CH (OC (O) -R · 3 ·) - DOLLAR A with R · 3 · hydrogen, C¶1-20¶-alkyl , C¶6-18¶-aryl, C¶7-20¶-alkaryl, C¶7-20¶-aralkyl DOLLAR A with amines of the general formula (III) DOLLAR A HNR · 1 · R · 2 · DOLLAR A and Hydrogen. |
