<jats:title>Abstract</jats:title><jats:p>The reactions of [BF<jats:sub>4</jats:sub>]<jats:sup>–</jats:sup> salts with Me<jats:sub>3</jats:sub>SiCN were studied at different temperatures and in the presence of several different Lewis acids, which led to the generation of the well‐known [BF<jats:sub>4–<jats:italic>n</jats:italic></jats:sub>(CN)<jats:italic><jats:sub>n</jats:sub></jats:italic>]<jats:sup>–</jats:sup> (<jats:italic>n</jats:italic> = 1–4) salts. Depending on the catalyst and the reaction conditions, the whole series of [BF<jats:sub>4–<jats:italic>n</jats:italic></jats:sub>(CN)<jats:italic><jats:sub>n</jats:sub></jats:italic>]<jats:sup>–</jats:sup> salts is now accessible under ambient conditions, and long preparation times and the excessive production of waste materials can be avoided. The best results were obtained when the F<jats:sup>–</jats:sup>/CN<jats:sup>–</jats:sup> substitution reactions were performed in ionic liquids.</jats:p>
