Reaction of Acetone on Coodinated Nitrile in beta-Diketonato Ruthenium Complex,[Ru(acac)_2(CH_3CN)_2]with the formatin of Beta-Ketiminate

摘要

Synthesis and characterizatin of a new ruthenium complex,[Ru(acac)_2(mhmk)](1)with coordinated beta-ketiminate ligand are described.The complex has bene obtained by the reaction of acetone on coordinated acetonirile in [Ru(acac)_2(CH_3CN)_2],the first such reactin to be observed.X-ray strucure of 1 is similar to that of [Ru(acac)_3].Cyclic voltammetric studies of 1 show a negative shift for both reduction and oxidation indicating that there is large electron density on ruthemium containing beta-ketiminate ligand when compared to ruthenium containing only beta-diketonato ligands,[Ru(acac)-3].
