  Synthesis of π-Conjugated Molecules Based on 3,4-Dioxypyrroles via Pd-Mediated Decarboxylative Cross-Coupling

  摘要：

  A general scheme for the synthesis of pi-conjugated molecules based on 3,4-dioxypyrroles is presented. The pi-conjugated molecules were synthesized via Pd-mediated decarboxylative cross-coupling using various 3,4-propylenedioxypyrrole carboxylic acids and aryl bromides, including the base-sensitive electron acceptor 4,7-dibromobenzo[c][1,2,5]-thiadiazole (BTD). N-Methylpyrrolidone was used as solvent, Pd(acac)(2) was employed as the palladium source and P(o-tol)(3) as the ligand. The methodology was applied to 3,4-dioxypyrrole monoacids and 3,4-dioxypyrrole diacids to produce multi-ring pi-conjugated systems containing phenyl, thiophenyl, BTD, and pyridinyl units. In general, the method has yielded a practical approach for the synthesis of 3,4-dioxypyrrole-based pi-conjugated molecules in acceptable to high yields of 44-94%.

  3,4-Propylenedioxypyrrole-Based Conjugated Oligomers via Pd-Mediated Decarboxylative Cross Coupling

  摘要：

  An effective decarboxylative cross-coupling involving a 3,4-dioxypyrrole is reported. Several conjugated oligomers were synthesized in high yields using various aryl bromides. No copper salt or other transmetalating agent was required. The reaction conditions employed displayed relatively low sensitivity toward the presence of water.

• Dioxypyrrole-Based Polymers via Dehalogenation Polycondensation Using Various Electrophilic Halogen Sources

  A convenient and efficient deiodination polycondensation method for the synthesis of dioxypyrrole-based (XDOP) polymers is reported. N-Halosuccinimides, iodine, and bromine were evaluated as halogenating agents to produce 2,5-halodioxypyrroles in situ via halodecarboxylation of 3,4-dioxypyrrole-2,5-dicarboxylic acids, which were then polymerized at 60 degrees C using dichloromethane or chloroform as solvent. When iodine and N-iodosuccinimide were employed as electrophilic halogen sources, the methodology produced macromolecules (M-n = 6.2-22.9 kDa) in satisfactory yields (55-71%) for two N-alkyl-3,4-dialkyloxypyrrole-based monomers that were tested. This method can be employed to produce a variety of XDOP-based homopolymers and regioregular copolymers starting from discrete oligomers under relatively mild reaction conditions.
