Ziegler and Natta were jointly awarded the 1963 Nobel Prize for Chemistry. Because of its commercially sensitive nature, much of the voluminous literature on this subject is in the form of patents, but a great deal of work has also been directed at ascertaining the mechanism of the catalyst. ...
In subject area:Chemistry Enantioselective catalysts are soluble metal complexes containing chiral ligands that create a chiral environment around the active metal center, allowing for the synthesis of optically pure compounds with high enantioselectivity. ...

The oxidative conversion of propane over Li/MgO catalysts follows a mixed heterogeneous-homogeneous radical chemistry where the catalyst acts as an initiator. At low propane partial pressures (0.1 bar), the catalyst surface area to volume ratio of the catalytic reactor does not influence the chain ...
