spiro-ansa-spiro-Phosphazenes were investigated for their DNA binding, antimicrobial activities and cytotoxic, apoptotic, and necrotic effects on fibroblast and lung cancer cells.
Two new ligands containing -N=N-group, 4-((E)-(4-bromophenyl)diazenyl)-2-((E)-(phenylimino)methyl)phenol (L 1 H 2), 4-((E)-(4bromophenyl)diazenyl)-2-((E)-((4-ethylphenyl)imino)methyl)phenol (L 2 H 3) and their metal complexes were synthesized. The synthesized metal complexes were performed as catalysts for the chemical fixation of CO 2 into cyclic carbonates using epoxides which 10 were used as both substrate and solvent. According to analytical, UV-visible and IR data, the metal complexes are formed by coordination of the N, O atoms of the ligands and metal:ligand ratio was found to 1:2 for all the complexes. TG and DTA results showed that these complexes had good thermal stability. Molecular structures of the ligand (L 1 H 2) and its Zn II complex 4 (Zn(L 1 ) 2 )were determined by single crystal X-ray diffraction studies. After choosing the best active catalyst (Zn(L 1 ) 2 4), the optimization studies were performed by changing various parameters. Ionic Liquid has been found to have a positive effect and showed the best active performance 15 with (bmim)PF 6 + Zn(L 1 ) 2 4 as binary catalytic system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
