Three-step synthesis of end-substituted pentacenes.
A concise, three-step synthesis of 1,4,8,11-substituted 2,3,9,10-tetrakis(methoxycarbonyl)pentacenes from commercially available 1,2,4,5-tetrakis(bromomethyl)benzene was established. Efficient alkynylation, followed by formation of four fused rings via a zirconacyclopentadiene intermediate, and then...
