10-phenanthrolines bearing one or two 2-(1-adamantyloxy)ethylamino substituents attached to different positions of the heterocyclic core were prepared according to SN Ar or palladium-catalyzed amination reactions. Their reaction with cis-Ru(bpy)2 Cl2 (bpy=2,2'-bipyridine) was investigated and Ru(bpy)2 (L)(PF6 )2 (phen=1,10-phenanthroline) (L=amino-substituted 1,10-phenanthroline) complexes were obtained in good yields
Two series of copper(I) complexes with diethoxyphosphoryl-substituted 1,10-phenanthroline ligands were synthesized and characterized in the solid state and in solution. The first comprised mixed-ligand CuI complexes with phenanthroline and triphenylphosphine. The second series includes bis-chelates with two phenanthroline ligands. According to the X-ray data for the six complexes, the ditopic phenanthroline
合成了两个系列的铜 (I) 配合物与二乙氧基磷酰基取代的 1,10-菲咯啉配体,并在固态和溶液中表征。第一种包括与菲咯啉和三苯基膦的混合配体 CuI 复合物。第二个系列包括具有两个菲咯啉配体的双螯合物。根据六种配合物的 X 射线数据,双位菲咯啉配体通过两个系列中的两个氮原子与铜 (I) 原子呈双齿配位。通过 1 H 和 31 P NMR 光谱、电化学和光谱电化学研究了涉及不同菲咯啉铜 (I) 物种的溶液平衡。这两个系列的这些不稳定配合物的溶液形态不同,取决于溶剂的性质和菲咯啉骨架上磷取代基的位置。配位溶剂可以取代金属中心内部配位球中的溴化物、三苯基膦,甚至菲咯啉配体。即使在 CH2Cl2 和 CHCl3 等非配位溶剂中,铜 (I) 与 α-取代的菲咯啉的配合物也很容易解离。在使用的溶液条件下观察到导致较少空间位阻物种的配体交换反应。菲咯啉螯合剂的配位模式在任何使用的溶液条件下都不会改变,并

intramolecular amination of thiophene rings following the reduction of a nitroalkene moiety directly attached to the S-heterocyclic ring. Optimization of the ligand and reaction conditions allowed the synthesis of a series of thienopyrroles aryl/alkyl-substituted at either the 2- or 3-position of the pyrrole ring. By using low pressures of carbon monoxide (5 bars), high yields of fused bicyclic compounds have been
