Perfluorinated Trialkoxysilanol with Dramatically Increased Brønsted Acidity

The Brønsted acidity of the perfluorinated trialkoxysilanol {(F(3)C)(3)CO}(3)SiOH is more than 13 orders of magnitude higher than that of orthosilicic acid, Si(OH)(4), and even more for most previously known silanols. It is easily deprotonated by simple amines and pyridines to give the conjugate sil...

description The Brønsted acidity of the perfluorinated trialkoxysilanol {(F(3)C)(3)CO}(3)SiOH is more than 13 orders of magnitude higher than that of orthosilicic acid, Si(OH)(4), and even more for most previously known silanols. It is easily deprotonated by simple amines and pyridines to give the conjugate silanolates [OSi{OC(CF(3))(3)}(3)](−), which possess extremely short Si−O bonds, comparable to those of silanones.
