摘要: Abstract A synthesis of five functional multidendate ligand: methyl 2-(bis((3,5-dimethyl-1 H –pyrazol-1-yl)methyl)amino)acetate L1 , -pyrazol-1-yl)methyl)amino)-propanoate L2 2-(bis((3,5-dimethyl-1H-pyrazol-1-yl) methyl) amino)-3-methylbutanoate L3 amino)-3-methyl- pentanoate L4 and 6-(bis((3,5-dimethyl-1 -pyrazol-1-yl)methyl)amino)hexanoate L5 is reported. Copper (II) complexes these compounds were examined for their catalytic properties. The in situ generated copper suitable catalysts the oxidation catechol substrate to quinone with dioxygen at ambient condition. All catalyze reaction rate varying from a high 11.8250 μmol L −1 min L2[Cu(CH 3 CO 2 ) ] complex weaker 0.7875 μmol L L3[Cu(NO .
