oxidation of 2-aminophenol (H2AP) to 2-amino-phenoxazine-3-one (APX), which revealed phenoxazinone synthase activity. DFT steric maps were utilized to understand the catalytic activity of 1 (% Vbur, 71.3%) and 2 (% Vbur, 75.6%). The current results clearly demonstrate an interesting structure–function relationship based on the effect of the ligand backbone on the geometry.
单核非血红素铜( II )化合物[Cu(BQEN)(CH 3 CN)] 2+ 1和[Cu(BQPN)(CH 3 CN)] 2+ 2 (BQEN = N , N ′-二甲基- N , N ′ -di(quinolin-8-yl) ethaneane -1,2-diamine; BQPN = N , N' -dimethyl- N , N'-di(quinolin-8-yl)propane-1,2-diamine) were synthesed and通过元素分析、ESI-MS、EPR 和单晶 X 射线衍射法表征。化合物1结晶于P空间群,而2结晶于P 2 1 / n组。化合物1和2表现出扭曲的四方金字塔几何结构,有趣的是,它们分别与1和2中的规则四方金字塔结构相差 4.8% 和 46.0% 。这归因于2中配体碳链主链的边际增加。化合物1和2用于将 2-氨基苯酚 (H 2 AP) 空气氧化为 2-氨基-吩恶嗪-3-酮
