Chengdu Institute of Biology, Chinese Academy of Sciences, Chengdu, China
Diphenylmethanes were prepared from the coupling of substituted toluenes themselves and from the cross‐coupling of substituted toluene and aromatic in the presence of bromine in anhydrous CCl4 under irradiation with moderate to good yields. The methylene moiety in diphenylmethanes comes from the toluene with fewer electron‐donating groups, and regioselectivity was observed.
