Abstract

Abstract : HSi(SiCl 3 ) 3 is a strong Brønsted acid … … that is more than 43 times stronger than HSiMe3 and even slightly stronger than HCl in acetonitrile. In their Communication onpage 16490 ff., S. Ketkov, S. Mebs, J. Beckmann, and co‐workers show that the deprotonation of HSi(SiCl3 )3 with an N‐heterocyclic carbene leads to the formation of Si(SiCl3 )3 −, a weakly coordinating anion
