In organic chemistry, a nitrone is a functional group consisting of an N-oxide of an imine. The general structure is {{chem2|R^{1}R^{2}C\dN+(\sO−)(\sR^{3})}}, where R3 is not a hydrogen. Their primary application is intermediates in chemical synthesis. A nitrone is a 1,3-dipole used in cycloadditions, and a carbonyl mimic.
