用^(13)C-NMR研究菲咯啉钌配合物的取代效应

Study on Substituent Effect of Ruthenium (Ⅱ) Tris 1, 10 Phenanthroline Complexes by 13 C NMR Spectra

用微波辐射法合成了Ｒｕ（５Ｘｐｈｅｎ）２＋３（Ｘ＝Ｈ，ＣＨ３，Ｃ６Ｈ５，Ｃｌ，ＮＯ２）系列配合物，测定并归属了这些配合物的１３ＣＮＭＲ光谱．

The complexes of ruthenium (Ⅱ) with 5 substituted 1,10 phenanthroline,Ru(5 X phen) 2+ 3 (where X=H,CH 3,C 6H 5,Cl,NO 2),were synthesized by microwave inrradiation method. 13 C NMR spectra of these complexes were determined and assigned by comparing their spectra with that of free ligand and combining off resonance decoupling (OFR) method.The chemical shifts are affected by the substituents on the phen in a direction consistent with that expected from the electron withdrawing ability of the substituent.
