N,N'-二(4,4,6,6-四甲基-4-哌啶基)-1,6-己二胺的合成

初步探讨了以三丙酮氨与己二胺为原料合成Ｎ，Ｎ－二（２，２，６，６－四甲基－４－哌啶基）己二胺，并对不同的工艺路线和反应的影响因素如催化剂、温度等进行了研究，发现以Ｐｄ／Ｃ为催化剂的一步法有着明显的三丙酮氨开环副反应，给出复杂的反应混合物。

Crystal Structure of Trinitratotri(Butylcaprolactam) Terbium(Ⅲ) Tb[■C_4H_9]_3(NO_3)_3

Tb[CH_2(CH_2)_4CONC_4H_9]_3(NO_3)_3,Mr=821.92. It is monoclinic,space group P2_1/c,a=18.604(2), b=9.768(1),c=21.887(3),β=96. 06(1)°,V=3955. 4(8),Z=4,Dc=1.43 g/cm￣3, MoKα radiation,μ=23.19 cm-1,F(000)=1760, R=0.039 for 2982 reflections with I>3σ(I).Tb(Ⅲ) is coordinated by three carbonyls of the three organic ligands and three bidentate nitrate groups. So each Tb(Ⅲ) is coordinated by nine oxygen atoms to form a distorted tricapped trigonal prism.
