Abstract The selective synthesis of [6]-, [8]-, and [10]cycloparaphenylenes (CPPs) was achieved by a new synthetic route involving Ni(0)-mediated coupling bis(para-haloaryl)dinuclear arylplatinum complexes the reductive elimination complexes. Importantly, highly strained [6]CPP prepared in good overall yield.
