## Abstract The synthesis of poly(2,5‐dialkoxy‐__p__‐phenylene)s (PPP) by palladium‐catalyzed polycondensation of 2,5‐dialkoxy‐4‐bromophenylboronic acids is described. Number‐average degrees of polymerization of ca. 30 have been reached at best. The characterization of the polymers by NMR, IR, UV‐V
