资源简介：
A ruthenium(II) flavonolate
complex, [RuII(bpy)2fla][BF4], was
synthesized to model the reactivity of the flavonol dioxygenases.
The treatment of dry CH3CN solutions of [RuII(bpy)2fla][BF4] with dioxygen under light leads
to the oxidative O-heterocyclic ring opening of the coordinated substrate
flavonolate, resulting in the formation of [RuII(bpy)2(carboxylate)][BF4] (carboxylate = O-benzoylsalicylate or benzoate) species, as determined by electrospray
ionization mass spectrometry. Moderation of the excitation and temperature
allowed isolation and characterization of an intermediate, [RuII(bpy)2bpg][BF4] (bpg = 2-benzoyloxyphenylglyoxylate),
generated by the 1,2-addition of dioxygen to the central flavonolate
ring.
