N2 - Substrate immobilization on graphite felt for solid-phase acetylene coupling reaction was achieved by electrochemical polymerization of the substrate precursor containing a pyrrole side chain, where the amount of substrate on the electrode surface was easily controlled by the number of repeated cyclic voltammetric scannings. Couplings between terminal acetylenes and the iodobenzene-modified graphite felt electrode or aromatic iodides and the terminal acetylene-modified graphite felt electrode in the presence of palladium catalyst proceeded smoothly in satisfactory yields.
