Abstract
Abstract
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.
