Abstract

Conditions for low-temperature Kumada–Corriu cross-coupling of polychlorinated acenes with Grignard reagents are reported. Our work was motivated by a search for cross-coupling reactions effective in the synthesis of functionalized linear acenes for organic materials applications. Treatment of polychlorinated acenes with the PEPPSI-IPr catalyst and MeMgBr undergo 6–8 concurrent coupling reactions to yield products such as ...
