Abstract: 

We present a new protocol for pyrene synthesis via transition-metal cross-couplings. The initially prepared 2,6-bis(phenylethynyl)biphenyls were transformed to pyrenes with uncommon 4,10-disubstitution through an electrophilic cyclization. The precursors were synthesized by Suzuki–Miyaura cross-coupling, which provides 2,6-dibromobiphenyls; these were subsequently coupled with phenylethynyl derivatives via Kumada cross-coupling.
