A new synthetic route to dihydrobiphenylenes has been developed. The process involves a mild Ru II ‐catalyzed [2+2+2] dimerization of ortho ‐alkenylarylacetylenes or its more versatile variant, the Ru‐catalyzed [2+2+2] cycloaddition of ortho ‐ethynylstyrenes with alkynes. Mechanistic aspects of this [2+2+2] cycloaddition are discussed.
