3,4-Propylenedioxypyrrole-based conjugated oligomers via Pd-mediated decarboxylative cross coupling.
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.
