A series of novel cyano-bridged mixed-valent copper complexes with different nuclearities, where the cyanide group is obtained from the cleavage of a carbon-carbon (C-C) bond in acetonitrile under mild conditions, have been prepared and structurally characterized via a completely in situ synthetic method. The method is catalyzed by 2,2'-bipyridine and 1,10-phenanthroline-based Cu(II) complexes ...

Reaction of the linear thorocene with NC(-), N3(-) and H(-) led to the bent derivatives [(Cot)2Th(X)](-) (X = CN, N3) and the bimetallic [{(Cot)2Th}2(μ-H)](-), whereas only [(Cot)2U(CN)](-) could be formed from (Cot)2U.

We report a survey of the reactivity of the first isolable iron-hydride complexes with a coordination number less than 5. The high-spin iron(II) complexes [(beta-diketiminate)Fe(mu-H)] 2 react rapidly with representative cyanide, isocyanide, alkyne, N 2, alkene, diazene, azide, CO 2, carbodiimide, and Brønsted acid containing substrates. The reaction outcomes fall into three categories: (1) add...

The implementation of more stringent regulations and the recent development of the International Cyanide Management Code (ICMC) by the industry is aimed at avoiding future environment incidents with cyanidation plants. To meet the ICMC discharge to tailings requirements and/or regulations, many operations now adopt cyanide recovery or destruction processes. In Australia, there is also the repor...

Catalysts applied in cobalt-catalyzed cyclotrimerizations reactions general rely on the use of Co(I) precatalysts or situ generation catalysts from Co(II) sources by reduction presence steering ligands, often addition less noble metals. In this paper, we report synthesis and properties novel stable CpCo(III) complexes as their exemplary evaluation for application catalytic [2+2+2] cycloaddition...

All the published stability constants of cyanocomplexes of metal ions, and the acidic dissociation constants of hydrogen cyanide, and those of the protonated metal complexes are critically surveyed. Unfortunately, a great fraction of data is unreliable and only a few thermodynamic data could be classified to the category of recommended values. The reasons of this situation are thorougly treated...
