## Abstract When a 1° or 2° alcohol solution of benzophenone and 2,4‐pyridinedicarbonitrile (**1**) is irradiated, the 2,4‐dicyanopyridinyl radical (**2**) is formed immediately. When the irradiation is performed in the cavity of an ESR spectrometer, the spectrum amplitude increases to a near stead
