The equations have been written in terms of H₃O+ and OH- as the acid and base catalysts, respectively, and these are certainly the most important catalysts in aqueous solution. ... Lewis acids can exert a catalytic effect in two different ways. ... For example, the polymerization of olefins by Lewis acids, such as boron trifluoride BF₃ aluminum chloride AlCl₃ and titanium tetrachloride TiCl₄ is believed to be caused by their interaction with proton acids ....  3, record 1, English, - acid%20catalysis

La théorie de Lewis a également révolutionné la théorie et la technique de la catalyse acide : beaucoup d'acides de Lewis, comme AlCl₃, BF₃, FeBr₃, se sont révélés actifs dans des réactions qui étaient catalysées par des acides aussi classiques que les acides de Brönsted, HF et H₂SO₄, par exemple.  2, record 1, French, - catalyse%20acide
