通过氟烷基化的1,3-二酮与乙二胺氢氯酸盐的直接相互作用制备了2,3-二氢-1 H -1,4-二氮杂pine;类似地,已经从氟化的1,3-酮酯获得了1,2,3,4-四氢-1,4-二氮杂-5-酮。在温和的条件下,发现氟化的1,3-二酮铜(II)和N(N)的铜(II)和N'-亚乙基双(氨基乙烯基酮)会与乙二胺反应生成含氟烷基的N,N' -亚乙基双(氨基乙烯基酮)和/或2,3-二氢-1 H -1,4-二氮杂s 。

2,3-Dihydro-1H-1,4-diazepines and 1,2,3,4-tetrahydro-1,4-diazepin-5-ones were obtained by direct condensation of fluorine-containing 1,3-diketones and 1,3-keto ethers, respectively, with ethylenediamine monohydroperchlorate. The structure of the compounds was confirmed by H-1 NMR, mass spectrometry and molecular weight determination.
