For the first time, we report experimentally and theoretically that nitroaromatic compounds, 2,4‐dinitrobenzenethiol and 4‐chloro‐2‐nitrobenzenethiol, on silver sols can be selectively reduced to 2‐amino‐4‐nitrobenzenethiol and 2‐amino‐4‐chlorobenzenethiol simply by irradiating with a visible light in ambient conditions, and the selective photoreduction is a very facile process. The results of quantum chemical calculations are in good agreement with our experimental data. Copyright © 2012 John Wiley & Sons, Ltd.
