FIELD: chemistry.SUBSTANCE: invention relates to a method of producing tertiary amines, particularly a novel method of hydrogenating enamines, which can be used in laboratory conditions and enables to obtain saturated tertiary amines of general formula,;,,.The method of hydrogenating enamines is characterised by that the enamines used are: 2-methyl-3-(N-piperidino)propene, 2-methyl-3-(N-morpholino)propene, 1-(N-piperidino)cyclohexene-1, 1-(N-morpholino)cyclohexene-1 or 1,4-dicyclohex-1-enylpiperazine, and hydrogenation is carried out with hydrogen at atmospheric pressure in the presence of a catalyst in form of nickel nanoparticles obtained by reducing nickel (II) chloride with sodium borane in situ, in a medium of isopropanol at temperature of 40-70°C for 5-6 hours.EFFECT: simple and cheap method of producing compounds of the disclosed structural formula.1 cl, 5 ex |
