A convenient and general method for Suzuki–Miyaura double cross-coupling of various dibromothiophenes was developed. Using a simple and cheap catalytic system Pd(OAc)2/PPh3 in 95% EtOH, various (hetero)arylboronic acids react with dibromothiophenes providing diarylthiophenes, useful in the synthesis of metal–organic frameworks (MOFs), in moderate to excellent yields.
