Silica‐Supported 1st Row Transition Metal (Nano)Catalysts: Synthetic and Catalytic Insight

Transition metal thiolates : synthetic , catalytic , and biomimetic aspects

Preparative methods, X-ray structures, and relevant spectroscopic cata are summarized for new bisand tris-complexes of chelating dithiolates of Nb(V) and Ta(V). Similarly, tetrakis(arenethiolat0) complexes of divalent transition metals are described. Reactivity of some of these complexes was examined to find novel homogeneous catalysis, e.g. condensation of dithiols. Peptide thiolate complexes ...

An insight into fluorescent transition metal complexes.

The emission from transition metal complexes is usually produced from triplet excited states. Owing to strong spin-orbit coupling (SOC), the fast conversion of singlet to triplet excited states via intersystem crossing (ISC) is facilitated. Hence, in transition metal complexes, emission from singlet excited states is not favoured. Nevertheless, a number of examples of transition metal complexes...

Catalytic Degradation of Benzene over Nanocatalysts containing Cerium and Manganese

A Ce-Mn composite oxide possessing a rod-like morphology (with a fixed molar ratio of Ce/Mn=3:7) was synthesized through a hydrothermal method. Mn ions were doped into a CeO2 framework to replace Ce ions, thereby increasing the concentration of oxygen vacancies. The formation energies of O vacancies for the Ce-Mn composite oxide were calculated by applying density functional theory (DFT). The d...

Synthetic development and chemical reactivity of transition-metal silylene complexes.

A variety of transition-metal complexes with terminal silylene ligands have become available in recent years, because of the discovery of several preparative methods. In particular, three general synthetic routes to these complexes have emerged, on the basis of anionic group abstraction, coordination of a free silylene, and alpha-hydrogen migration. The direct transformation of organosilanes to...
