The reactivity of carbonyl‐tris(trifluoromethyl)borane (CF 3 ) 3 BCO against the homologous series of cyanogen (pseudo)halides NCX, X = F, Cl, Br, I, CN, was investigated. Lewis acid‐base adducts (CF 3 ) 3 BNCX were obtained for X = Cl, Br, I, CN and were characterized by vibrational and NMR spectroscopy. It appeared that FCN did not react and twofold complexation of NCCN does not occur, in agreement with theoretical complexation energies and QTAIM charges.
