Iminium

An iminium salt or cation in organic chemistry has the general structure [R¹R²C=NR³R⁴]⁺ and is as such a protonated or substituted imine ^[1]. It is an intermediate in many organic reactions such as the Beckmann rearrangement, Vilsmeier-Haack reaction, Stephen reaction or the Duff reaction. The use of the alternative names imonium compounds and immonium compounds is discouraged.
