Beschreibungen/Notizen

• The reactions of [BF4]– salts with Me3SiCN were studied at different temperatures and in the presence of several different Lewis acids, which led to the generation of the well‐known [BF4–n(CN)n]– (n = 1–4) salts. Depending on the catalyst and the reaction conditions, the whole series of [BF4–n(CN)n]– 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–/CN– substitution reactions were performed in ionic liquids. In the presence of Lewis acidic catalysts, salts bearing cyanidofluoridoborates of the type [BF4–n(CN)n]– can be prepared in bulk under mild conditions in good yields without the production of large amounts of waste materials.
