Synthesis and characterization of β-diketonato ruthenium(II) complexes with two 4-bromo or protected 4-ethynyl-2,2′-bipyridine ligands
摘要:
Two new mononuclear mixed-ligand ruthenium(II) complexes with acetylacetonate ion (2,4-pentanedionate, acac) and functionalized bipyridine (bpy) in position 4, [Ru(bpyBr)(2)(acac)](PF(6)) (2; bpyBr = 4-Bromo-2,2'-bipyridine, acac = 2,4-pentanedionate ion) and [Ru(bpyOH)(2)(acac)](PF(6)) (3; bpyOH = 4-[2-methyl-3-butyn-2-ol]-2,2'-bipyridine) were prepared as candidates for building blocks. The (1)H NMR, (13)C NMR, UV-Vis, electrochemistry and FAB mass spectral data of these complexes are presented. (C) 2010 Elsevier B.V. All rights reserved.
