A practical route to triarylmethanes: Sulfamic acid was found to efficiently catalyze Friedel–Crafts alkylations of 2‐methyl furan or 1, 2, 4‐trimethoxybenzene with a variety of simple or functionalized aldehydes to provide di‐ or triarylmethanes in high yields. The reaction tolerated variety of substitutions and functional groups under “open‐flask”, mild and solvent‐free conditions. Moreover, the Sulfamic acid can be conveniently recycled is especially noteworthy.
