identified a cationic species, supported by a THF molecule, as the best Lewisacid precatalyst for a range of Diels–Aldercycloadditions. This highlighted the importance of fully isolating and characterizing the active species in any catalytic process especially when Lewisacids are used due to the presence of hidden Brønsted acids (HBAs). Finally, the control experiments conducted in order to eliminate
