Triarylmethanes, which are valuable structures in materials, sensing and pharmaceuticals, have been synthesized starting from methylphenylsulfone as an inexpensive and readily available template. The three aryl groups were installed through two sequential palladium‐catalyzed CH arylation reactions, followed by an arylative desulfonation. This method provides a new synthetic approach to multisubstituted
