FIELD: chemistry.
SUBSTANCE: method involves reaction of bisamine with 3-fold excess acetylene in the presence of a vanadyl acetylacetonate (VO(acac)2) catalyst in an argon atmosphere at temperature 70°C and atmospheric pressure for 3 hours, followed by addition of diisobutylaluminium hydride and stirring the reaction mixture for 4-6 hours at room temperature. The method enables to obtain N1,N1,N4,N4-tetramethyl-2-butene-1,4-diamine from available reagents with quantitative output of (82-97%).
EFFECT: high output of end product.
