Direct observation of 4-alkoxyphenylnitrenium ions upon irradiation of 4-alkoxyphenyl azides in aqueous solution
Abstract
Photolysis of 4-ethoxy- and 4-methoxy-phenyl azide in aqueous solution results in quantitative formation of 4-ethoxy- and 4-methoxy-phenylnitrenium ions which have lifetimes of ∼ 1 µs.
