摘要
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.
