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