Evidence of hydrogen migration in an alkylphenyldiazirine excited state.
Ultrafast photolysis (350 nm) of alkylphenyldiazirines promotes the diazirine to the S(1) excited state. Solvent and substituent effects on the excited state lifetimes indicate that the S(1) state is highly polarized and undergoes a [1,2]-H shift in concert with nitrogen extrusion in cyclohexane.
