Interactive 3D chemistry animations of reaction mechanisms and 3D models of chemical structures for students studying University courses and advanced school chemistry hosted by University of Liverpool
The alkaline solution is modified by adding a monovalent metal salt, e.g., sodium chloride, which prevents the clay from swelling which decreases the permeability of the formation. After substantially all of the ammonium ions are removed, the formation is then flushed with water to remove any ...
Molar quantities of catalyst are generally required, as metal complexes are formed with both the acyl halide and the carbonyl product. Exceptions include the reactions of electron-rich aromatic systems which can often be acylated in the presence of small amounts of milder Lewis acids or in the ...

The algorithm is demonstrated for reaction mechanism elucidation of transition metal catalysts. We highlight how to explore catalytic cycles in a systematic and reproducible way. The exploration objectives are fully adjustable, allowing one to harness the STEERING WHEEL for both structure-specific (...

limit their applicability and accuracy for a particular system of interest; transition metal complexes are good examples owing to their variability in valency and generally intricate electronic structures. On the other hand, a class of approaches22,37,62,63requires a manual setup of reactivity trials...
It has seen that superoxide anion (O2•−) is the reactive species of oxygen with the lowest oxidizing capacity, but this can go through an electron transfer and generate hydrogen peroxide (H2O2), and therefore participate in the reaction of Fenton and, in the presence of reduced metal ion...

The proposed triazole–diazoimine equilibrium results in the formation of highly reactive azavinyl metal-carbene 13, which reacts with isothiocyanate 14, causing an apparent swap of 1,2,3-triazole core for thiazole imine. A sulfonyl group is often used to protect N−H moiety of nitrogen-...
