dipyridylpyrrolato (dpp−)–metal complexes. The meridial tridentate dpp− ligand is a useful anionic analogue of the terpyridyl ligand. The first (dpp)Ru complexes are described; the 3,4‐substitution of the central pyrrole significantly perturbs the potentials of the redox processes of these complexes. A [(dpp)Ru(bpy)(MeCN)]+ (bpy=2,2′‐bipyridine) complex is an electrocatalyst for the reductive disproportionation of
通过直接将2-吡啶基甲醛(2当量),α-亚甲基酮与2-吡啶基甲醛缩合获得在吡咯核心的C3和C4位置取代的各种2,5-二(2-吡啶基)吡咯(dppHs)。至少一个吸电子取代基和乙酸铵。还表征了新颖的2,5-二(1,10-菲咯啉-2-基)吡咯。dppHs可直接快速进入二吡啶基吡咯烷酮(dpp -)-金属配合物。该三齿meridial DPP -配体是三联吡啶配体的有用的阴离子类似物。描述了第一个(dpp)Ru络合物;中心吡咯的3,4-取代极大地干扰了这些配合物的氧化还原过程。A [(dpp)Ru(bpy)(MeCN)] + (bpy = 2,2'-联吡啶)络合物是用于二氧化碳还原歧化为一氧化碳和碳酸根离子的电催化剂。
