Resourceful resorcinarene: Imidazolium salts based on a rigid resorcinarene platform are used as catalyst precursors in Suzuki–Miyaura cross-coupling reactions, fostering higher catalytic activity than precursor salts devoid of a cavity. The Pd centres of the catalysts obtained from the precursors are found to locate preferentially outside the cavity and the presence of a bulky resorcinarenyl substituent seems to favor the reductive elimination step.
