From Proton to Boron: The Lewis Analogs of Protonated Brønsted Super Acids

Résultats de recherche: Contribution à un journal/une revueArticleRevue par des pairs


Isolation and characterization of highly reactive intermediates are crucial to understand the nature of chemical reactivity. Accordingly, the reactivity of weakly coordinating anions (WCA), usually used to stabilized cationic super electrophiles are of fundamental interest. When a variety of WCA are known to form stable σ-complexes with a proton, inducing Brønsted super acidity, bis-coordinated weak-coordinated anions are much more elusive and considered as long-sought reactive species. In this work, the chemistry of borylated sulfate, triflimidate and triflate anions were scouted in details with the aim of synthetizing the unique analogs of protonated Brønsted superacids. Those complexes were formed by successive borylation with a 9-boratriptycene derived Lewis super acid paired with a weak coordinated anion, characterized in solution and in the solid state and exhibit unique structures and reactivities.
