Preparation and investigation of the spectral and electrochemical properties of mixed-ligand ruthenium(II) complexes containing 1,8-naphthyridines was written by Staniewicz, Robert J.;Sympson, Robert F.;Hendricker, David G.. And the article was included in Inorganic Chemistry in 1977.Related Products of 322-46-3 This article mentions the following:
Mixed-ligand complexes of the form Ru(bpy)2L2+ and Ru(phen)2L2+, L = 1,8-naphthyridine (napy), 2,7-dimethyl-1,3-naphthyridine, 2-methyl-1,8-naphthyridine, and pyrido[2,3-b]pyrazine, and bpy is 2,2′-bipyridine and phen is 1,10-phenanetroline were prepared and isolated as their PF6- salts. The formulations were confirmed by elemental and anal. and conductivity measurements while the purity of the compounds was judged by the single maximum observed in the a.c. polarograms. The solution spectra of the mixed-ligand complexes are characterized by a high-intensity (ε â?04) metal-to-ligand charge-transfer band at â?50 nm and Ï â?Ï* intraligand UV transitions. The energies and intensities of these absorptions are compared with previously reported Ru(byp)2X22+ complexes. The reduction potentials (Ru3+/Ru2+) for the napy mixed-ligand complexes were determined using both cyclic voltammetry and a.c. polarog. and the reversibility of the electrochem. couples was established. The E1/2 values do not vary greatly from those observed for the (phen)3- and (bpy)3Ru(II) complexes thus indicating that the stability of the Ru(II) state has not been significantly altered by the replacement of a phen or bpy with a napy type ligand. In the experiment, the researchers used many compounds, for example, Pyrido[2,3-b]pyrazine (cas: 322-46-3Related Products of 322-46-3).
Pyrido[2,3-b]pyrazine (cas: 322-46-3) belongs to pyrazine derivatives. Pyrazine heterocycles and their benzo derivatives possess many interesting properties, including chemical reactivity profiles, and have diverse applications in total synthesis, medicine, chemical biology, materials, dyes, and imaging. Pyrazine-based skeletons were incorporated into agents targeting a range of ailments. Many derivatives were synthesized and evaluated as potential cancer treatments.Related Products of 322-46-3
