Nitrenium ion
Introduction
A nitrenium ion (also called: aminylium ion) in organic chemistry is a reactive intermediate based on nitrogen with both an electron lone pair and a positive charge and with two substituents (R2N+) [1]. The compound can have both a singlet and a triplet state.
Aryl nitrenium ions are currently investigated because of their involvement in certain DNA damaging processes. These intermediates can have microsecond or longer lifetimes in water [2].
Nitrenium ions are also intermediates in organic reactions for instance the Bamberger rearrangement. They can also act as electrophiles in electrophilic aromatic substitution [3].
The term imidonium ion with the same meaning is now obsolete.
