Abstract:

ABSTRACT Cyanase catalyzes the decomposition of cyanate into CO2 and ammonium, with carbamate as an unstable intermediate. The cyanase of Pseudomonas pseudoalcaligenes CECT5344 was negatively regulated by ammonium and positively regulated by cyanate, cyanide, and some cyanometallic complexes. Cyanase activity was not detected in cell extracts from cells grown with ammonium, even in the presence of cyanate. Nevertheless, a low level of cyanase activity was detected in nitrogen-starved cells. The cyn gene cluster of P. pseudoalcaligenes CECT5344 was cloned and analyzed. The cynA, cynB, and cynD

ABSTRACT A bacterial strain able to use cyanide as the sole nitrogen source under alkaline conditions has been isolated. The bacterium was classified as Pseudomonas pseudoalcaligenes by comparison of its 16S RNA gene sequence to those of existing strains and deposited in the Colección Española de Cultivos Tipo (Spanish Type Culture Collection) as strain CECT5344.

Abstract:

The oxidation of cyanide by peroxide in alkaline aqueous solution is catalysed by copper complexes. In the presence of excess cyanide, copper(II) is reduced to form the tricyanocuprate (I) complex. The cyanogen oxidation product is hydrolysed with disproportionation to cyanate and cyanide:2CuII+2CN-→ 2CuI+(CN)2(CN)2+2OH- → OCN-+CN-+H2OCuI+3CN- ↔ Cu(CN)32-The stoichiometry and kinetics of the catalysed oxidation have been investigated. Hydrogen peroxide oxidizes coordinated cyanide with a rate that is first order in peroxide and first order in copper but independent of cyanide concentration in

The cyanoacetylide complex Fe(C≡CC≡N)(dppe)Cp (3) is readily obtained from sequential reaction of Fe(C≡CSiMe3)(dppe)Cp with methyllithium and phenyl cyanate.

In the case of the 36-electron complexes [Cp(dppe)Fe-C≡CC≡N-MLn]n+, spectroscopic and structural data are consistent with a degree of charge transfer from the iron centre to the rhodium or ruthenium centre via the C3N bridge, giving rise to a

We report a simple and versatile approach to assemble sensitive and selective fluorescence “turn-on” sensors for cyanide by combining three off-the-shelf materials; namely fluorescent dye, 1-vinyl imidazole polymer, and cupric chloride. The cyanide-sensing species is a non-fluorescent fluorophore-polymer-Cu2+ complex; which forms as a result of the imidazole polymer’s ability to bind both fluorophore and fluorescence quencher (Cu2+). Cyanide removes Cu2+ from these complexes; thereby “turning-on” sensor fluorescence. These sensors are water-soluble and have a detection limit of ~2.5 μM (CN−) i

We recently found that certain cyanines form tight complexes with carboxymethylamylose (CMA) in aqueous solutions and that in these complexes the cyanine exists as a strongly fluorescent and stable J-aggregate. Cyanine dyes are characterized by their ability to form J-aggregates showing very narrow absorption and fluorescence spectra relative to the monomer. Although they have found uses in sensing applications, the practicability has been limited in many cases due to the low quantum efficiencies for J-aggregate fluorescence. The CMA-cyanine complex is formed by a cooperative self-assembly in

Abstract:

Leads to the cellular effects of the anti-arthritic gold complexes may come from the determination of their metabolism by target cells and, possibly, cells in the immediate environment of the target cells. Polymorphonuclear leukocytes (PMN) and mononuclear cells (monocytes and lymphocytes) are present in inflamed joints of patients with rheumatoid arthritis and these cells have been widely used in pharmacological studies on the gold complexes. It is suggested that the cellular effects of the gold complexes are mediated by the production of aurocyanide. According to this hypothesis, PMN metabol

Abstract:

Cyanide is one of the most potent and toxic chemicals produced by industry. The jewellery industry of Córdoba (Spain) generates a wastewater (residue) that contains free cyanide, as well as large amounts of cyano–metal complexes. Cyanide is highly toxic to living systems because it forms very stable complexes with transition metals that are essential for protein function. In spite of its extreme toxicity, some organisms have acquired mechanisms to avoid cyanide poisoning. The biological assimilation of cyanide needs the concurrence of three separate processes: (i) a cyanide-insensitive respira

The reaction between (tht)AuCl (tht = tetrahydrothiophene) and KCN leads to gold(I) cyanide.

The cyclohexylamine complex was also obtained as the adduct LauCN L and the pyrrolidine complex in the ionic form [L2Au]+ [Au(CN)2]-. Two polymorphs of the 3,5-lutidine complex were obtained.

Iron-cyanide complexes are present in soil and ground water due to anthropogenic inputs. We compared the adsorption of ferricyanide ion, on two commercial activated carbons (COM3 and COM4) and γ-alumina (A1G) in aqueous solution. Isotherm parameters obtained from batch experiments of iron-cyanide complex adsorption on these adsorbents were carried-out. The mass of the adsorbents were varied at 40 mg, 60 mg and 100 mg and the inorganic ion initial concentrations, Coalso varied between 3.04×10-4and 2.43×10-3mol/L.

Abstract:

The possibility of nucleophilic addition of 4-nitropyrazole (4-NO2-pz) to a pseudohalide group present in the coordination sphere of a central atom was investigated. Ten products were isolated from M(II)-X--4-nitropyrazole systems with M = Cu, Ni or Co and X = NCO, N(CN)2 or C(CN)3, and investigated by infrared and electronic spectroscopy. Four of these compounds were pseudohalide complexes, two were complexes with anionic chelate ligands formed by nucleophilic addition, and the remaining products were mixtures of pseudohalide and chelate complexes. The [Cu(NCO)2(4-NO2-pz)2] complex is rhombic

Abstract:

Charge-transfer interactions of octaethylporphycenatozinc(II), ( OEPc ) Zn with 2,6-dichloro-3,5-dicyano-1,4-benzoquinone, DDQ, in non-aqueous solvents are reported. Both optical absorption and cyclic voltammetry studies reveal the formation of stable charge-transfer complexes between ( OEPc ) Zn and DDQ. New redox couples corresponding to reduction of the charge-transfer complex have been electrochemically detected. The formation of charge-transfer complexes between ( OEPc ) Zn and doubly reduced DDQ is examined and the present electrochemical studies reveal the possible existence of such com
