摘要：Two new mononuclear Ru complexes Ru(II)(bipa)(pic)3 (1; H2bipa = 6-(1H-benzo[d]imidazol-2-yl)picolinic acid, pic = 4-picoline) and Ru(II)(pbic)(pic)3 (2; H2pbic = 2-(pyridin-2-yl)-1H-benzo[d]imidazole-7-carboxylic acid, pic = 4-picoline) based on anionic ligands were successfully synthesized, and characterized using NMR spectroscopy, mass spectrometry, and X-ray crystallography. These catalysts showed high activities and stabilities in water oxidation in homogeneous systems with a high turnover number of 2100 and a turnover frequency of 0.21 s(-1) for complex 1. The O-O band formation mechanism involved water nucleophilic attack. An active catalytic intermediate, i.e., Ru(IV)-OH, was detected using high-resolution mass spectrometry.
