Electric Literature of C22H17N3. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 4-(p-Tolyl)-2,2:6,2-terpyridine, is researched, Molecular C22H17N3, CAS is 89972-77-0, about Synthesis, characterization and DNA-binding studies of new tridentate polypyridyl cobalt(II) and ruthenium(II) complexes. Author is Yang, Hao; Chen, Wen-Tao; Qiu, Dong-Fang; Bao, Xiao-Yu; Xing, Wen-Ru; Liu, Shan-Shan.
Two novel tridentate polypyridyl mixed-ligand complexes of cobalt(II) and ruthenium(II), [Co(TolylTPy)(H2Bzimpy)]Cl2 [TolylTPy = 4′-p-tolyl-2,2′:6′,2″”-terpyridine, H2Bzimpy = 2,6-bis(benzimidazol-2-yl)pyridine] (A) and Ru(TolylTPy) (Bzimpy) (B) were synthesized and characterized by elemental anal., IR and 1H NMR. The crystal structure of complex B was determined The interactions between the complexes and calf thymus DNA have been investigated by absorption and fluorescence spectroscopies. The photoactivated cleavage of pBR322 DNA by the complexes was studied. The spectrophotometric studies suggested that both complexes A and B bind to DNA by electrostatic interactions. The agarose gel electrophoresis showed that complex A converted supercoiled pBR322 DNA to nicked and linear DNA when it was irradiated at 310 nm for 15 min.
