Synthesis and Characterization of Organometallic Cyanides and Phthalocyanines
pi-arene complexes of octaalkoxyphthalocyanines and metallophthalocyanines were prepared by reaction of soluble phthalocyanine (H2PcOR) and metallophthalocyanine (M(PcOR)) ligands with Cp*Ru(NCMe)3 +. The molecular structure of {Cp*Ru[eta6-Ni(PcOBu)]}PF 6 consists of a dimer of two cofacially …

Reactions at coordinated ligands: redox-active ligands and coordination of Lewis acids
… two cyanide ligands, however, models using cyanides ligands are plagued by undesirable side reactions such as metal-cyanide bridged polymers and decomposition. The bound boranes are used to simulate the hydrogen bonding found in the enzymes. The complexation of Lewis acids to cyanides offers …

Sviluppo di tecnologie alternative per il trattamento biologico di reflui ad elevato contenuto di azoto
… simultaneous presence of toxic compounds like cyanides, phenols and sulfides. The wastewater is currently treated at full scale by steam stripping up to a final NH4-N concentration of 25 mg/L: if NH4-N level in the effluent from the stripping unit can be set at 2,000 mg/L and treated by the …

Requirements for Cell-Free Cyanide Oxidation by Pseudomonas Fluorescens NCIMB 11764
The involvement of cyanide oxygenase in the metabolism of pyruvate and a-ketoglutarate-cyanohydrin was investigated and shown to occur indirectly by the consumption of free cyanide arising from the cyanohydrins via chemical dissociation. Thus, free cyanide remains the substrate, for which the …

Bacterial Cyanide Assimilation: Pterin Cofactor and Enzymatic Requirements for Substrate Oxidation
Utilization of cyanide as the sole nitrogen source by Pseudomonas fluorescens NCIMB 11764 (Pf11764) occurs via oxidative conversion to carbon dioxide and ammonia, the latter satisfying the nitrogen requirement. Substrate attack is initiated oxygenolytically by an enzyme referred to as cyanide …
