Condensation reactions of three isomers of bis(diethylenetriamine)cobalt(III) with formaldehyde and ammonia were studied. The s-fac isomer gave a main product containing two molecules of the cyclic amine, 1,3,5,8-tetraazacyclodecane. It was unstable in acidic solution to give several decomposition products. The encapsulated complex in which all the nitrogens were attacked by formaldehyde could not be
摘要研究了双(二亚乙基三胺)钴(III)三种异构体与甲醛和氨的缩合反应。s-fac异构体得到的主要产物包含两个分子的环胺1、3、5、8-四氮杂环癸烷。在酸性溶液中不稳定,会产生几种分解产物。无法获得其中所有氮都被甲醛侵蚀的包封的配合物。u-fac异构体的主要产物是半包封的配合物,即四个伯氨基中的三个与甲醛和氨反应生成3-(7-氨基-2,5-二氮杂庚基)钴(III)配合物)-1,3,5,8-四氮杂环癸烷。所述异构体异构体给出了1,4,7,9,11,14,17-庚七氮杂十七烷的配合物,以及与来自u-fac异构体的反应产物相同的反应产物。
