Preparation, structure and electrochemistry of heterometallic Ru(II) and Fe(II) complexes
Four ruthenium(II) complexes containing ferrocene-based ligands, Ru(acac)2(dppf) (1), Ru(acac)2(eta2-O2CFc) (2), Ru(PPh3)2(eta2-O2CFc)2(3) and Ru(dppf)(eta2-O2CFc)2(4) have been prepared by the reaction of Ru(acac)2(CH3CN)2with 1,1-bis(diphenylphosphino)ferrocene or Ru(PPh3)3Cl2with ferrocenecarboxylic acid in the presence of sodium bicarbonate. In these complexes, the Ru center is chelated by the dppf ligand or bound with the ferrocenecarboxylate moiety in a eta2fashion. All the complexes were characterized by microanalyses,1H and31P{1H} NMR, ESI-MS, IR, and UV?Vis spectroscopy. The solid state structure of complex 1 was confirmed by X-ray crystallography. Cyclic voltammetry measurements in dichloromethane for all complexes display reversible or quasi-reversible Ru and Fe couples with significant coupling. Two one-electron oxidation waves were observed in the cyclic voltammetry of 3 and 4 due to the stepwise oxidation of [Fe2II,II] into [Fe2II,III]+and [Fe2II,III]+into [Fe2III,III]2+.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.COA of Formula: C34H28FeP2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 12150-46-8, in my other articles.
