Aerobic oxidative coupling of 2-naphthol derivatives catalyzed by a hexanuclear bis(μ-hydroxo)copper(II) catalyst

A novel hexanuclear bis(μ-hydroxo)copper(II) complex, [L3(Cu2(μ-OH)2)3](ClO4)6 (1), was synthesized with dinucleating ligand N,N,N,N-tetra(pyridin-2-ylmethyl)-m-xylene diamine (L). Complex 1 is fully characterized by X-ray crystallography and magnetic susceptibility in the solid state and UV-vis and electron paramagnetic resonance spectroscopy in solution. The molecular structure of 1 possesses three dicopper cores, in which two copper centers are bridged by two hydroxide groups and separated by a distance ranging from 2.8852(15) to 2.8937(10) ?. In addition, the three dicopper cores are linked by the dinucleating ligand between each pair of adjacent dicopper cores. Importantly, aerobic oxidative coupling of 2,4-di-tert-butylphenol, 2-naphthol, and six 2-naphthol derivatives was achieved in 33-96% yield using complex 1 as a catalyst.

Dual signal (color change and fluorescence ON-OFF) ensemble system based on bis(Dpa-CuII) complex for detection of PPi in water

We have developed simple dual signal (color change and fluorescence ON-OFF) ensemble systems based on a bis(Dpa-CuII) complex 1 for the detection of PPi in water. Dual signal takes place because of weak binding and fluorescence quenching effect

Selective fluorescent detection of flavin adenine dinucleotide in human eosinophils by using bis(Zn2+-dipicolylamine) complex

A novel fluorescent sensor based on the Zn2+-DPA complex shows selective detection of flavin adenine dinucleotide (FAD) from among other flavins in water, and it was used to detect FAD in eosinophils by fluorescence microscopy and FACS. Copyrig

Regioselective hydroxylation of the xylyl linker in a diiron(III) complex having a carboxylate-rich ligand with H2O2

Reaction of a diiron(III) complex having a xylta4- ligand (N,N,N′,N′-m-xylylenediamine tetraacetate) with H2O2 resulted in regioselective hydroxylation of the m-xylyl linker. The reaction mimics the self-hydroxylation of a

A highly sensitive gold nanoparticle-based colorimetric probe for pyrophosphate using a competition assay approach

In this study, a mixture of [Zn2(1,3-bis[bis(2-pyridylmethyl) aminomethyl]benzene)]4+ ([Zn2(BBPAB)]4+) and 11-mercaptoundecylphosphoric acid functionalized gold nanoparticles (Phos-AuNPs) is shown to be a highly sensitive colorimetric probe that can easily detect pyrophosphate (PPi) at less than 200 nM with the naked eye.

Novel asymmetrically functionalized bis-dipicolylamine metal complexes: Peripheral decoration of a potent anion recognition scaffold

We report the design and synthesis of a novel class of asymmetrically functionalized, ditopic bis-dipicolylamine (BDPA) ligands. A key feature of this research involved the controlled, sequential functional group decoration of a potent molecular recognition scaffold. Calorimetric screening identified a BDPA analogue as a highly potent (Ka～ 106 M-1) and selective sensor for inorganic phosphate.

Dinucleotide hydrolysis promoted by dinuclear Zn complexes - The effect of the distance between Zn ions in the complexes on the hydrolysis rate

The rate of hydrolysis of an RNA dimer, uridylyl(3′→5′)uridine (UpU), promoted by dinuclear Zn complexes resulting from a series of ligands with differently spaced Zn ion binding sites, was examined. Although the ligands in the present study have in common two di-2-pyridylmethylamino moieties as the Zn binding sites, the activities of these ligands toward the hydrolysis were quite different. Our results suggest that the distance between metal ion coordination sites is an essential factor for the intrinsic activities of the dinuclear complexes.
