fundamental interest in chemical and biological processes. We provide here a detailed account of the reaction of O 2 with dicopper(I) complexes, involving O 2 -reversible binding, followed by the stoichiometric aromatic hydroxylation of the ligand. Thus, tricoordinated dicopper(I) complexes [Cu 2 (R-XYL)] 2+ (R=H, MeO, t-Bu, F, CN, NO 2 ; 1a-f possess dinucleating meta-substituted xylylene ligands with two
双氧 (O 2 ) 与铜离子中心结合后的结合和随后的反应性在化学和生物过程中具有重要意义。我们在此详细介绍了 O 2 与二铜 (I) 配合物的反应,涉及 O 2 可逆结合,然后是配体的化学计量芳族羟基化。因此,三配位二铜 (I) 配合物 [Cu 2 (R-XYL)] 2+ (R=H, MeO, t-Bu, F, CN, NO 2 ; 1a-f 具有双核间位取代的二甲苯配体和两个螯合三齿双[2-(2-吡啶基)乙基]胺(PY2)部分和5-R取代基
