Calcium carbonate-gold nanocluster hybrid spheres: Synthesis and versatile application in immunoassays

Fluorescent gold nanoclusters (AuNCs) were incorporated into porous calcium carbonate spheres through electrostatic interaction. The resulting CaCO 3/AuNCs hybrid material exhibited interesting properties, such as porous structure, excellent bi

Mercury(ii)-stimulated oxidase mimetic activity of silver nanoparticles as a sensitive and selective mercury(ii) sensor

Research on oxidase mimics is challenging but important. In this article, mercury(ii) ion enabled citrate-capped silver nanoparticles (Cit-AgNPs) exhibit catalytic activity toward the oxidation of typical chromogenic substrate 3,3′,5,5′-tetramethylbenzidi

Electrochemical oxidation of o-phenylenediamine and 1,3 dihydrospiro[benzo[d]imidazole-2,1′-cyclohexane]. A comprehensive study and introducing a novel case of CE mechanism

Electrochemical behavior of o-phenylenediamine (PDA) and 1,3-dihydrospiro[benzo[d]imidazole-2,1′-cyclohexane] (DBI) was extensively studied in water and water/ethanol mixture using different voltammetric techniques. Our data showed that the oxidation of P

Iodine(III)-Mediated, Controlled Di- or Monoiodination of Phenols

An oxidative procedure for the electrophilic iodination of phenols was developed by using iodosylbenzene as a nontoxic iodine(III)-based oxidant and ammonium iodide as a cheap iodine atom source. A totally controlled monoiodination was achieved by buffering the reaction medium with K3PO4. This protocol proceeds with short reaction times, at mild temperatures, in an open flask, and generally with high yields. Gram-scale reactions, as well as the scope of this protocol, were explored with electron-rich and electron-poor phenols as well as heterocycles. Quantum chemistry calculations revealed PhII(OH)·NH3 to be the most plausible iodinating active species as a reactive "I+" synthon. In light of the relevance of the iodoarene moiety, we present herein a practical, efficient, and simple procedure with a broad functional group scope that allows access to the iodoarene core unit.

PH-tuned metal coordination and peroxidase activity of a peptide dendrimer enzyme model with a Fe(ii)bipyridine at its core

Peptide dendrimer BP1 was obtained by double thioether bond formation between 5,5′-bis(bromomethyl)-2,2′-bipyridine and two equivalents of peptide dendrimer N1 (Ac-Glu-Ser)8(Dap-Glu-Ala)4(Dap-Amb- Tyr)2Dap-Cys-Asp-NH2

Kinetic characterisation of o-aminophenols and aromatic o-diamines as suicide substrates of tyrosinase

We study the suicide inactivation of tyrosinase acting on o-aminophenols and aromatic o-diamines and compare the results with those obtained for the corresponding o-diphenols. The catalytic constants follow the order aromatic o-diamines max/KmS, follows this order: o-diphenols > o-aminophenols > aromatic o-diamines.

Photochemistry of phenyl azides bearing 2-hydroxy and 2-amino groups studied by matrix-isolation spectroscopy: Generation and characterization of reactive o-quinoid compounds

Broad-band irradiation (λ > 370 nm) of 2-hydroxyphenyl azide (1) in Ar at 10 K monitored by IR resulted in the formation of at least three major products, all of which were shown to be photointerconvertible under these conditions. The two products showing

Matrix isolation of o-quinoid compounds - 6-imino-2,4-cyclohexadien-1-one and 1,2-diimino-3,5-cyclohexadiene

6-Imino-2,4-cyclohexadien-1-one (1b) and 1,2-diimino-3,5-cyclohexadiene (1c) were generated in high yields from o-azidophenol (5b) and o-azidoaniline (5c), respectively, by irradiation in argon matrices at 10 K or by flash vacuum pyrolysis (FVP) with subsequent trapping of the products in solid argon. The hydrogen shift in the phenylnitrenes 6 formed as primary intermediates is very rapid, and thus the nitrenes are short-lived transients even under the conditions of matrix isolation. Ring expansion to azacycloheptatetraenes was not observed. FVP produces the thermodynamically most stable E/Z isomers of the quinones as the main products. Photolysis of the matrix-isolated quinones results in photostationary equilibria of the E/Z isomers. The stereoisomers were identified by comparison of the matrix IR spectra with ab initio calculations at the RMP2-FC-6/31G(d) level of theory. VCH Verlagsgesellschaft mbH, 1996.
