资源简介：
Two new anthyridine-based ligands,
5-phenyl-2,8-bis(2-pyridinyl)-1,9,10-anthyridine (L3) and 5-phenyl-2,8-bis(6′-bipyridinyl)-1,9,10-anthyridine
(L4), were designed for accommodation
of dimetallic systems with the metal ions separated by ∼5 Å.
Complexation of Cu(ClO4)2 with L3 and L4 provided the corresponding dicopper complexes [{Cu2(L3)(H2O)4(CH3CN)2}(ClO4)4] (3) and [{Cu2(L4)(μ-ClO4)2}(PF6)2] (4), respectively. Both complexes were characterized by spectroscopic
methods, and the detail structural features were further confirmed
by X-ray crystallography. Structural analyses of 3 and 4 reveal the Cu···Cu distances in the complexes
being 4.9612(7) and 5.013 (2) Å, respectively. Both complexes
are active in the catalytic oxidation of benzyl alcohols into the
corresponding aldehydes. Furthermore, complex 4 appears
to be a good catalyst for the oxidative coupling of primary alcohols
into the corresponding esters with the use of hydrogen peroxide as
the oxidant in an aqueous medium. The possible cooperative interactions
between the metal ions during the catalysis are discussed.
