Conclusions 1. A method was developed for the synthesis of 1,4-N,N-bis(alkylamino)butanes and 1,4-diazacyclooctanes by the hydrogenation of the corresponding 1,4-N,N-bis(alkylamino)-1,3-butadienes and 1,4-diaza-5,7-cyclooctadienes. The latter were obtained from diacetylene, alkylamines, and alkylenediamines. 2. The hydrogenation of the 1,4-N,N-bis(alkylamino)-1,3-butadienes and 1,4-diaza-5,7-cyclooctadienes is accompanied by hydrogenolysis of the C-N bond. Cleavage of the C-O bonds occurs during the hydrogenation of the di(β-cyanoethyl) ethers of glycols. 3. The method for obtaining the di(γ-aminopropyl) ethers of glycols by the hydrogenation of the corresponding dinitriles was modified. The reaction was run in the absence of ammonia at an initialhydrogen pressure of 160–180 atm.
