Perfluorinated Trialkoxysilanol with Dramatically Increased Bronsted Acidity.

ABSTRACT: The Brønsted acidity of the perfluorinated trialkoxysilanol {(F₃ 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(CF₃ )₃ }₃ ]^- , which possess extremely short Si-O bonds, comparable to those of silanones.
