The random synthesis of [5n]- and [7m]cycloparaphenylenes (CPPs) (n = 2–4 and m = 2–3) and the selective synthesis of [14]CPP were achieved in four and six steps, respectively, by the nickel- or platinum-mediated cyclizations of the penta- and hepta-ring units containing cis-1,4-bis(triethylsiloxy)-2,5-cyclohexadiene-1,4-diyl and the H2SnCl4-mediated aromatization of the triethylsilyl-protected cyclohexadienediol. [20]- and [21]CPPs were synthesized for the first time.
