The reactive intramolecular frustrated Lewis pair (FLP) Mes 2 PCH 2 CH 2 B(C 6 F 5 ) 2 reacts rapidly with thionyl chloride to yield the zwitterionic chlorination product [Mes 2 PCl + ]CH 2 –CH 2 [BCl(C 6 F 5 ) 2 – ]. Analogous zwitterionic products were obtained by the reaction of the FLP with chlorine or bromine. Compounds [Mes 2 PX + ]CH 2 CH 2 [BX(C 6 F 5 ) 2 – ] (X = Cl, Br) were characterized by X‐ray crystal structure analyses.
