= LB = 6,6′-bis(phenylselanyl)-2,2′-bipyridine. The research objective was to evaluate the potential of these compounds to activate ground-state molecular oxygen to form higher-valent Ru–O–Se bonds by cleavage of the O–O bond of O2. All of the compounds prepared indeed activated O2 to form Ru–O–Se moieties, as observable by UV/Vis spectroscopy, mass spectrometry, or X-ray crystallography.
各种钌 (II) 与通式 [RuIILALB]X2 LA = LB = 6,6'-双[(4-甲氧基苯基)硒基]-2,2'-联吡啶的近端亲氧苯基硒基团的配合物;6,6'-双[(硝基苯基)硒基]-2,2'-联吡啶;3,6-双(苯基硒基)双吡啶并[3,2-a:2',3'-c]吩嗪;制备了 LA = 6,6'-双(苯基硒基)-2,2'-联吡啶,LB = 三联吡啶}。与先前报道的具有 LA = LB = 6,6'-双(苯基硒基)-2,2'-联吡啶的化合物相比,这些化合物的取代模式被设计为具有不同的吸电子/供电子特性或不同的结合基序. 研究目标是评估这些化合物通过裂解 O2 的 O-O 键来激活基态分子氧以形成更高价的 Ru-O-Se 键的潜力。
