An environmentally benign procedure is developed for the preparation of 4‐selanylpyrazoles from pyrazoles and diselenides. Using haloid salts as catalysts and H2O2 as oxidant, this catalytic protocol is convenient in water at room temperature under open‐air condition, and is suitable for a wide variety of starting materials and provides a series of 4‐selanylpyrazoles in good yields. A plausible catalytic
