Straightforward and regiospecific synthesis of 1,3,5,7-tetra-arylated acene bearing different aryl groups

Abstract

1,3,5,7-Tetra-arylated acene derivatives were synthesised by first introducing aryl groups at the 1,5-positions via cross-coupling reactions and then selectively introducing pentafluorophenyl groups at the 3,7-positions via CDC reactions.
