| Popis: | The interaction of aromatic amines with piperylene and its chlorine derivatives was being studied. Direct alkylation of aniline by piperylene in the presence of Lewis acids results in its C-substituted derivatives. At reaction of 4-chloro-2-pentene and 3,4-dichloro-2-pentene with arylamines in medium of excess aromatic amine, ring-substituted arylamines are formed due to proceeding Claisen’s amino-rearranging of initially formed N-substituted products. In medium of triethylamine, the same reaction is completed at the stage of N-alkenylation. The compounds obtained are of interest as substances with biological activity; at the same time they are valuable intermediates for the synthesis of nitrogen-containing heterocycles. |
