The reactivity of cyclic(Alkyl)(amino)carbenes (CAACs) with ZnMe 2 was studied. While adduct (CAAC)ZnMe 2 is highly reactive (to undergo a Zn−Me migration reaction), robust two‐coordinate (CAAC)ZnR + Lewis acidic cations were also prepared and characterized. Cation (CAAC)ZnC 6 F 5 + is an effective and selective catalyst for alkene, alkyne and CO 2 hydrosilylation. Its overall reactivity is essentially under charge control as it is only slightly affected by the electronic differences between CAAC and Arduengo‐type NHC ligands.
