Spirotriazolines and spirooxadiazolines are furnished in high yields at room temperature by the light-induced [3+2] cycloaddition with 2,5-diaryltetrazole as the precursor of nitrile imine. The use of light as the unique reagent and broad substrate scope are distinguishing features of this protocol.
