The Schmidt reaction of aldehydes with NaN3 furnishes the corresponding nitriles in near quantitative yields in the presence of TfOH and tolerates various electron-withdrawing and electron-donating substituents. Formanilides, common side products, are not observed. The reaction is easily scalable, high yielding, and nearly instantaneous.
