(4+3)-cycloaddition chemists of oxidopyridinium ions and related study
(University of Missouri--Columbia, 2019)The (4+3)-cycloaddition reaction is a cycloaddition between a 4-atom species and a 3-atom species to form a seven-membered ring. This reaction results in the formation of seven-membered rings. Our research expanded the ... -
Acrylate synthesis from carbon dioxide - ethylene coupling catalyzed by first-row transition metal complexes
(University of Missouri--Columbia, 2021)Carbon dioxide (CO2) is an abundant and renewable carbon source than can be used as feedstock for the synthesis of value-added materials. One such material is acrylic acid, and acrylate derivatives, which can be used in ... -
