FIELD: chemistry.
SUBSTANCE: invention relates to a method for synthesis of asymmetric 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 an equimolar amount of N,N,N1N1-tetramethyldiaminomethane (bisamine) in the presence of a catalyst 6-hydrate samaric nitrate (Sm(NO3)2*6H2O), taken in molar ratio of α,ω-diacetylene: bisamine: (Sm(NO3)2*6H2O) =10:10:(0.3-0.7), preferably 10:10:0.5 moles, without a solvent at temperature 80°C and atmospheric pressure for 3 hours, with subsequent addition to the reaction mass of gem-diamine R2NCH2NR2, where R2N is as defined above, in amount which is equimolar to bisamine and stirring the reaction mass for 3-5 hours. The asymmetric α,ω-di(aminomethyl)alkadiines can be used in fine organic synthesis, particularly for synthesis of scarce polycyclic compounds.
EFFECT: improved synthesis of said derivatives.
