摘要
A series of ruthenium compounds containing a pyrrole-ketone bidentate ligand, 2-(2-methoxybenzoyl)pyrrole (1), have been synthesized and characterized. Reacting 1 with [(η 6 -cymene)RuCl 2 ] 2 and RuHCl(CO)(PPh 3 ) 3 generated Ru(η 6 -cymene)[C 4 H 3 N-2-(CO-C 6 H 4 -2-OMe)]Cl (2) and {RuCl(CO)(PPh 3 ) 2 [C 4 H 3 N-2-(COC 6 H 4 -2-OMe)]} (3), respectively, in moderate yields. Successively reacting 2 with sodium cyanate and sodium azide gave {Ru(η 6 -cymene)[C 4 H 3 N-2-(CO-C 6 H 4 -2-OMe)]X} (4, X=OCN; 5, X=N 3 ) with the elimination of sodium chloride. Compounds 2–5 were all characterized by 1 H and 13 C-NMR spectra and their structures were also determined by X-ray single crystallography.
