METHOD OF PRODUCING α,ω-DI(AMINOMETHYL)ALKADIINES Russian patent published in 2012 - IPC C07C11/12 C07C11/22 C07C11/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing α,ω-di(aminomethyl)alkadiines of general formula (1) , where R₂N=piperidyl, morpholyl, N-methylpiperazyl, characterised by that α,ω-diacetylenes HC=C-(CH₂)_n-C≡CH, where n=4, 6, 8 react with gem-diamines R₂NCH₂NR₂, where R₂N is as described above, in the presence of a copper (I) chloride (CuCl) catalyst, taken in molar ratio α,ω-diacetylene: bisamine: CuCl=10:20:(0.3-0.7), preferably 10:20:0.5 mmol, at temperature 80°C and atmospheric pressure for 4-6 hours. α,ω-aminomethylated diacetylenes can be used in fine organic synthesis, particularly for producing hard-to-get polycyclic compounds.

EFFECT: method increases output of the desired products.
