(Figure Presented) Ultrafast photolysis (350 nm) of alkylphenyldiazirines promotes the diazirine to the S1 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.
A significant barrier to 1,2 hydrogen migration in singlet 1-phenylethylidene. A laser flash photolysis study

Laser flash photolysis of 1-phenyldiazoethane in heptane releases 1-phenylethylidene which can be intercepted with pyridine to form an ylide (λmax> = 475 nm). Oxygen trapping experiments indicate that relaxation of singlet 1-phenylethylidene to
