Abstract

An excellent linear relationship is obtained between the relative reactivities of the carbonyl compounds in the triethylsilyl perchlorate- and perchloric acid-catalyzed reduction by triethylsilane, demonstrating that identical catalytic mechanisms are operative in both the Brønsted acid (perchloric acid) and the Lewis acid (triethylsilyl perchlorate) systems in solution.
