 A nitrogen bound to both a good electrofuge and a good nucleofuge is known as a nitrenoid (for its resemblance to a nitrene).Nitrenes lack a full octet of electrons are thus highly electrophilic; nitrenoids exhibit analogous behavior and are often good substrates for electrophilic amination reactions.Nitrenoids can be generated from "O"-alkylhydroxylamines containing an N-H bond via deprotonation or from "O"-alkyloximes via nucleophilic addition.
