| 摘 要： | A ring-contracted form macrocycle, 29,30-dioxo-3,6,9,17,20,23,29,30-octaazapentacyclo[23,3,1,1^11,15,0^2,6,0^16,20]-triacontaneocta- 1 (28),9,11 (12), 13,15(30),23,25(29),26-ene (L) was synthesized by condensation of diethyltriamine with pyridine-1-oxide-2,6-dicarboxaldehyde. A porous three-dimensional layer structure in its crystal was formed by self-assembly through hydrogen bonds and π-π interaction. Its dinuclear copper(I) complex [Cu2L(MeOH)2]-(BF4)2*2H2O and dinuclear-copper(II) complex [Cu2L(MeOH)2](ClO4)4*2H2O were obtained and could oxidize catalytically four phenolic substrates hydroquinone, 2-methyl-hydroquinone, 2,6-di-tert-butylphenol and 2,6-dimethylphenol, in a mixture of methanol and acetonitrile (V : V, 4 : 1). The copper(I) complex reacted with dioxygen to form an oxygenated species as an initial active intermediate for oxidation of the phenols. Oxidation of the substrates by the copper(II) complex produced a copper(I) complex and the oxidation products of the substrates. |

| Abstract: | A ring‐contracted form macrocycle, 29,30‐dioxo‐3,6,9,17,20,23,29,30‐octaazapentacyclo[23,3,1,111,15,02,6,016,20]‐triacontaneocta‐1(28),9,11(12),13,15(30),23,25(29),26‐ene (L) was synthesized by condensation of diethyltriamine with pyridine‐1‐oxide‐2,6‐dicarboxaldehyde. A porous three‐dimensional layer structure in its crystal was formed by self‐assembly through hydrogen bonds and π‐π interaction. Its dinuclear copper(I) complex [Cu2L(MeOH)2](BF4)2·2H2O and dinuclear‐copper(II) complex [Cu2L(MeOH)2](ClO4)4·2H2O were obtained and could oxidize catalytically four phenolic substrates hydroquinone, 2‐methyl‐hydroquinone, 2,6‐di‐tert‐butylphenol and 2,6‐dimethylphenol, in a mixture of methanol and acetonitrile (V:V, 4:1). The copper(I) complex reacted with dioxygen to form an oxygenated species as an initial active intermediate for oxidation of the phenols. Oxidation of the substrates by the copper(II) complex produced a copper(I) complex and the oxidation products of the substrates. |
