A ligand‐enabled Pd‐catalyzed Suzuki–Miyaura coupling of haloterthienyls for the synthesis of various thiophene‐based π‐conjugated oligomers including quinquethiophenes is demonstrated. An indolyl phosphine ligand plays an important role in this transformation. Thiopheneboronic acids were well applied, which might open up a window for the application of thiopheneboronic acids in the synthesis of thiophene‐based π‐conjugated oligomers in materials chemistry.
