Nitrilases have a high potential for application in organic chemistry, environmental technology, and analytics. However, their industrial uses require that they are produced highly active robust forms at reasonable cost. Some syntheses catalyzed by nitrilases already reached level of technological readiness. This has been enabled the large-scale production recombinant catalysts. Despite some pr...

Historically, antidotal potencies of cyanide antagonists were measured as increases in the experimental LD(50) for cyanide elicited by the antidotes. This required the use of high doses of cyanide following pre-treatment with the putative antidote. Since IACUC guidelines at our institutions strongly discourage LD(50) determinations: we developed a new test paradigm that allowed for maximal surv...

The R2PI-TOF spectra of supersonically expanded rare gas/chiral arene heteroclusters have been rationalized in terms of the distortion of the pi-electron density reflecting the different dipole and quadrupole momenta induced in the rare gas atoms by interaction with the opposite pi-faces of the chiral arene itself.

Reduction of [U(Ts(Tol))(Cl)(μ-Cl)U(Ts(Tol))(THF)2] [2, Ts(Tol) = HC(SiMe2NAr')3; Ar' = 4-MeC6H4)] with KC8 in toluene afforded the new arene-bridged diuranium complex [{U(Ts(Tol))}2(μ-η(6):η(6)-C6H5Me)] (3); combined structural, spectroscopic, magnetic, and computational analyses unambiguously confirm that the uranium centres in 3 are in the +5 oxidation state and the toluene is a 10π-tetraanion.

cyanide is one of the major environmental pollutants in industrial wastewater. entrance of it to existence environmental contains very health hazardous. the cyanide can be removed from aqueous solutions in many ways, but most of these methods are expensive. in the present study, novel magnetic nanoparticle modified with a polydentate ligand is used to remove cyanide. the procedure is efficient ...

addition of potassium cyanide to a mixture of schiff base and lithium perchlorate afforded a-aminonitriles in high yields. addition of potassium cyanide to a methanolic solution of schiff base and phosphoric acid afforded a-aminonitriles. when the reaction mixture was refluxed it gave a-amino acids in high yields.
