the oxidation of catechol to o -quinone for miming microorganism in the O2 activation for electrophilic non substituted aromatic. The in situ generated Cu(II), Fe(II) and Zn(II) complexes of these ligands ( L1 – L7 ) were examined for such catalytic activities. We found that all these substrates catalyze the oxidation reaction of catechol to o -quinone with the presence of atmospheric dioxygen. The
基于哒嗪酮和硫代哒嗪酮基团的一系列七个杂环化合物:5-(2-氯苄基)-6-甲基哒嗪-3-酮 L1 ; 5-[(2-氯苄基)羟基)甲基] 6-甲基哒嗪-3-酮 L2 ;5-(2-氯苄基)-2,6-二甲基吡啶并-3-一 L3 ; 5-(2-氯苄基)-2-(羟乙基)-6-甲基哒嗪-3-one L4 ;4-(2-氯-苄基)-3-甲基-6-氧并哒嗪-1(6H)-基)乙酸乙酯 L5 ; 5-(2-氯苄基)-2-(羟乙基)-6-甲基哒嗪-3-硫酮 L6 和乙基-4-(2-氯苄基)-3-甲基-6-硫代哒嗪-1(6H)-基)乙酸乙酯 L7 分别为儿茶酚至氧化测试 Ò -醌用于模拟微生物中O 2活化为亲电性非取代芳族化合物。检查了这些配体( L1 - L7 )的原位生成的Cu(II),Fe(II)和Zn(II)配合物的 催化活性。我们发现,所有这些底物在大气双氧存在下催化邻苯二酚氧化为 邻 醌。这种氧化的速率
