A simple, mild, and efficient synthesis of symmetric 3,6‐diarylpyridazine derivatives using a green catalytic one‐pot two‐step reaction of aryl methyl ketones, arylglyoxal monohydrates, and hydrazine hydrate was developed. Environmentally benign nature, high atom‐economy, no harmful byproduct, easy workup procedure, no column chromatography steps, and moderate to excellent yields of the products are the salient features of this new multicomponent‐based methodology.
