Based on the dramatic accelerating effect of 2-aminophenol, three ligands derived from 2-aminophenol were developed. Copper-catalyzed coupling reaction of nitrogen-containing nucleophiles with aryl bromides was efficiently carried out under mild conditions using 1,2,3,4-tetrahydro-8-hydroxyquinoline as a novel, simple, and versatile ligand.

The new copper(II) complexes [Cu4(pa)4(Bae)4]·H2O (1) and [Cu4(eba)4(Buae)4]·H2O (2) (Hpa = propionic acid, HBae 2-benzylaminoethanol, Heba 2-ethylbutyric acid HBuae 2-butylaminoethanol) were synthesizsed by the interaction of a copper salt with methanol solution respective ligands. single-crystal X-ray diffraction analysis reveals that both compounds have {Cu4(μ3-O)4} cubane-like core. Both sh...

a novel ternary schiff base ligand (hl) of ono type and its copper (ii) complex weresynthesised using 2-aminophenol and o-acetoacetotoluidide. they have been characterised by theusual analytical and spectral methods. the interaction of the complex with calf-thymus (ct)dna has been investigated by uv-vis, viscosity measurement, cyclic voltammetry anddifferential pulse voltammetry studies. the re...

An amperometric immunosensor was constructed by dispersing graphite, schistosoma-japonicum antigen (SjAg) and silica sol-gel at low temperature. The performance characteristics of the prepared immunosensor were examined in the buffered solution of o-aminophenol (o-AP) used as a substrate. It exhibited excellent physical and electrochemical stability with a renewable external surface. A competit...

To measure the ability of surviving tissue slices to form glucuronides of compounds such as menthol and phenol, Lipschitz & Bueding (1939) determined ether-soluble compounds giving the Tollens colour reaction for glucuronic acid. Whilst this procedure yielded valuable information in their hands, it is inconvenient for routine purposes, and the lack of specificity in the colour reaction can be a...
