This review covers our recent contribution on the synthesis of extended polyconjugated compounds, such as conjugated polymers and small molecules. The synthetic strategies developed in our research group are mainly based on palladium‐catalyzed cross‐coupling reactions involving a variety of organometallic intermediates as well as on direct arylation reactions via C–H functionalization. This report is organized according to the synthetic methods used (coupling of unsaturated organosilanes, Suzuki–Miyaura cross‐coupling, Stille cross‐coupling, direct arylation) and the typologies of the structures synthesized (polymers, small molecules).
