Different from the traditional multi-step synthesis, a chemoselective direct C–H arylation is reported for the single-step synthesis of various useful π–acceptor–π (π–A–π) type building blocks for use in organic electronics. This well-optimized C–H heteroarylation exhibits good product yields, broad substrate scope, and high functional group compatibility. Applications in the efficient synthesis of a new metal-free dye sensitizer for dye-sensitized solar cells (DSSCs) are also demonstrated. (Figure presented.).

A versatile phosphorus-containing π-conjugated building block, thieno[3,4-c]phosphole-4,6-dione (TPHODO), has been developed. The utility of this simple but hitherto unknown building block has been demonstrated by preparing novel functional organophosphorus compounds and bandgap-tunable conjugated polymers.
Acetic anhydride mediated condensation of aromatic o-diacid dichlorides with benzimidazoles to provide electro-reducible p-dione adducts

Acetic anhydride mediates a facile and rapid condensation of benzimidazole with aromatic o-diacid dichlorides to precipitate p-dione adducts in excellent yields. Condensation with pyridine-3,4-dicarbonyl dichloride produced a 1:1 mixture of isomeric p-diones. The X-ray crystal structure of one of the latter isomers revealed unusual high density, and inter-layer separation similar to graphite. Cyclic voltammetry demonstrated that p-dione is capable of two consecutive one-electron-reductions with formal potentials influenced by the fused (hetero)aromatic and substituent effects.
