In a single step, several variously functionalized [RuCp*(η6-arene)]+ sandwich complexes have been prepared starting from RuCl3·xH2O in yields ranging from 35 to 80%, referring to ruthenium. The protocol covers the preparation of valuable [RuCp*]+-complexed amino acids. In comparative experiments starting from the oligomer [RuCp*Cl2]n and using methanol/methanolate as the reducing agent, the formation
在一个步骤中,从 RuCl3·xH2O 开始,以 35% 到 80% 的产率(以钌为基准)制备了几种不同功能化的 [RuCp*(η6-arene)]+ 夹心配合物。该协议涵盖了有价值的 [RuCp*]+-复合氨基酸的制备。在从低聚物 [RuCp*Cl2]n 开始并使用甲醇/甲醇化物作为还原剂的对比实验中,观察到不需要的副产物的形成,这是由于邻氯茴香醚复合物的亲核取代和 Cp* 配体的甲氧基化. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
