monoaza-15-crown-5, diaza-12-crown-4, diaza-18-crown-6 ethers, and 1,4,7,10-tetraazacyclododecane having aromatic pendants were prepared by the reductiveamination of the corresponding macrocycles with aromatic carboxyaldehydes in the presence of NaBH(OAc)3. Reductiveamination under 1MPa conditions provided significant shortening of the reaction time and yield enhancements.

The variable-length azacrown ether bridging ligand N,N′-bis(3-pyridyl-methyl)diaza-18-crown-6 (b3pmdc) was reacted with cuprous iodide to give a range of new discrete and polymeric coordination compounds. Six structurally diverse CuI(b3pmdc) architectures were isolated, as well as a single oxidized CuII(b3pmdc) species. These include the helical one-dimensional (1D) chain [H4b3pmdc][Cu10I14]·CHCl3·2H2O
可变长度的氮杂皇冠氮桥键合配体N,N'-双(3-吡啶基-甲基)二氮杂18-皇冠-6(b3pmdc)与碘化亚铜反应生成一系列新的分立的和聚合的配位化合物。六个结构上不同的Cu I(b3pmdc)体系结构被隔离,以及一个单独的氧化的Cu II(b3pmdc)物种。这些包括螺旋一维(1D)链[H 4 b3pmdc ] [Cu 10 I 14 ]·CHCl 3 ·2H 2 O(1),发光线性簇链[Cu 4 I 6(H 2 b3pmdc)](2),客体含水网络[Cu 4 I 4(H b3pmdc)2 ](1.5ClO 4)(0.5I 3)·3.5H 2 O·2.5MeOH(3),发光古巴簇链[Cu 4 I 4(b3pmdc)2 ](4),三维(3D)网[Cu 9 I 12(K b3pmdc)3(H 2 O)4 ]·9MeOH(5),双核混合卤化物[Cu2 Cl 3.4 I 2.6(H 4 b3pmdc)](6),和1D铜链[CuCl
