Abstract

The reaction between [RhC5H4CO2(CH)2OH] (1) and 1,1'-carbonyldiimidazole (CDI) leads to the new CO2-imidazole functionalized alkoxycarbonylcyclopentadienyl complex [RhC5H4CO2(CH2)2O2C-Im] (2) (Im=imidazole). The latter was treated with five generations of poly(propylenimine) dendrimers DAB-dendr-(NH2)(n) [n=4, 8, 16, 32, 64] (DAB=diaminobutane) to accomplish the synthesis of the new organometallic dendritic macromolecules DAB-dendr-NH(O)COCH2CH2OC(O)C5H4Rh(NBD) [n=4 (4), 8 (5), 16 (6), 32 (7), 64 (8)] based on flexible poly(propylenimine) dendrimer cores, built up to the fifth generation. Spectroscopic characterization of all the new compounds will be presented and discussed.

摘要

[RhC5H4CO2(CH)2OH] (1) 与1,1'-羰基二咪唑 (CDI) 反应生成新型的经CO2-咪唑官能化的烷氧羰基环戊二烯基配合物 [RhC5H4CO2(CH2)2O2C-Im] (2)（Im = 咪唑）。后者与五代聚（丙烯亚胺）树枝状大分子DAB-dendr-(NH2)(n) [n = 4, 8, 16, 32, 64]（DAB = 二氨基丁烷）反应，以完成基于柔性聚（丙烯亚胺）树枝状大分子核且构建至第五代的新型有机金属树枝状大分子DAB-dendr-NH(O)COCH2CH2OC(O)C5H4Rh(NBD) [n = 4 (4), 8 (5), 16 (6), 32 (7), 64 (8)] 的合成。将展示并讨论所有新化合物的光谱表征。
