Reaction of sugar oxazolines with primary amines. In order to scrutinize the reaction pathway and structure of the reaction product, we started with a simple sugar oxazoline and a primary amine, carrying no other functional groups.
In one sense, an oxidizing agent is a chemical species that undergoes a chemical reaction that removes one or more electrons from another atom. In that sense, it is one component in an oxidationâreduction (redox) reaction. In the second sense, an oxidizing agent is a chemical species that transfers electronegative atoms, usually oxygen, to a substrate. Combustion, many explosives, and organic redox reactions involve atom-transfer reactions.
