Suzuki–Miyaura cross-coupling between (hetero)aryl (pseudo)halides and base-sensitive and Lewis-basic (hetero)arylboronic acids is challenging, owing to potential side reactions and catalyst poisoning. Now, the Suzuki–Miyaura cross-coupling of arylthianthrenium salts with (hetero)arylboronic acids, under acidic conditions, is reported, enabling the efficient coupling of base-sensitive and Lewis-basic (hetero)arylboronic acids.
