Superelectrophilic anion information


Figure 1: Sphere-rod model (boron cage framework (B) shown in pink and substituents (X = halogens, CN) shown in gray).

Superelectrophilic anions are a class of molecular ions that exhibit highly electrophilic reaction behavior despite their overall negative charge.[1][2] Thus, they are even able to bind the unreactive noble gases or molecular nitrogen at room temperature.[1][2][3] The only representatives known so far are the fragment ions of the type [B12X11] derived from the closo-dodecaborate dianions [B12X12]2–. X represents a substituent connected to a boron atom (cf. Fig. 1). For this reason, the following article deals exclusively with superelectrophilic anions of this type.
