A ligand‐free heterogeneous palladium on charcoal (Pd/C)‐catalyzed Suzuki‐Miyaura cross‐coupling has been performed. The series of substituted p‐terphenyls were prepared in very good yields without exclusion of air and with low catalyst loadings. Moreover, the developed environmentally benign and scalable protocol enables to use electron poor and sterically hindered boronic acids.
