WebJan 1, 1978 · Introduction In 1963 Dwyer's group reported the synthesis of [Ru (bipy)2C12] (bipy = 2,2'-bipyridyl) by the pyro- lysis of (bipyH) [Ru (bipy)C14] [1]. It was assumed that the reaction produced only the cis isomer. This complex is rather imnportant in that it is the starting point in a number of preparations and undoubtedly will continue to be ...
2,2′-Bipyridine (2,2′-bipy) is a chelating ligand that forms complexes with most transition metal ions that are of broad academic interest. Many of these complexes have distinctive optical properties, and some are of interest for analysis. Its complexes are used in studies of electron and energy transfer, supramolecular and materials chemistry, and catalysis. 2,2′-Bipyridine is used in the manufacture of diquat. WebThe aim of this work is to evaluate the effect of different transition metals (Ir, Rh, and Re), different ancillary ligands (bipy and CO), and -R groups (C[H.sub.3] and …

WebNov 1, 1995 · A consecutive reaction between two solids, CuCl 2 · 2H 2 O and 2,2′-bipyridyl, in a 1:2 molar ratio proceeds in two steps: CuCl 2 · 2H 2 O first converts to Cu (bipy)Cl 2, then Cu (bipy)Cl 2 turns into Cu (bipy) 2 Cl 2 · 2H 2 O. This is because the second step of the reaction is much slower than the first.
