FIELD: chemistry.
SUBSTANCE: method involves catalytic telomerisation of butadiene with diethylamine in the presence of a catalyst based on cationic complexes of palladium (II) of general formula [(acac)Pd(L)2]BF4 (where acac is an acetylacetonate ligand, L=PPh3, P'Pr3, P"Bu3 P(p-Tol)3 or (L)2=diphosphine ligands, selected from bis(diphenylphosphino)methane(dppm), bis(diphenylphosphino)propane(dppp), bis(diphenylphosphino)butane(dppb), bis(diphenylphosphino)ferrocene(dppf)). The process is carried out in a substrate medium, specifically diethylamine and butadiene, at temperature of 50-90°C. The method enables to obtain N,N-diethylocta-2,7-diene-1-amine with selectivity of 99.9% from the overall mixture of reaction products with high process output which reaches 4180 g of product per 1 g Pd. The catalysts used are more readily available compared to those previously used for the process.
EFFECT: improved method.
