2,6-Bis(phenylethynyl)biphenyls and their cyclization to pyrenes
MacHuy, Mareike M.,Wuertele, Christian,Schreiner, Peter R.
experimental part, p. 1405 - 1409 (2012/07/02)
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.

Direct CH bond arylation of arenes with aryltrimethylsilanes catalyzed by PdCl2 in the presence of CuCl2 as an oxidant has been developed. In addition to the role as the oxidant, CuCl2 is found to be necessary for the selective crosscoupling reaction.

Cationic gold(I) complexes having Buchwald-type biarylphosphines effectively catalyzed twofold hydroarylation of 2,6-dialkynylbiphenyls to construct pyrene skeletons.
