The formation of triphenylmethyl radical in the photolysis of triphenylmethyl azide is demonstrated by its esr spectrum. Photolysis of azide labeled in the terminal nitrogen with nitrogen-15 leads to isotope-position rearrangement, suggesting that recombination of triphenylmethyl and azide radicals occurs. Pyrolysis of the labeled azide results in extensive isotope-position rearrangement. No radicals can be detected in the pyrolysis products by esr measurement, however, so the rearrangement probably occuss by an intramolecular process or ion-pair recombination.
