Light can be used to cleave chemical bonds through the excited state, offering a powerful yet mild means to produce free radical species using traceless photons. However, in these reactions, specific irradiation wavelengths of light have been considered indispensable to achieve excitation through S₀–S_n or S₀–T_n transitions. Here, we report the photoinduced dissociation of electronegative interelement bonds by wavelengths of light much longer than theoretically and spectroscopically predicted for S₀–S_n or S₀–T_n transitions to enable various radical reactions under mild conditions.
