Diarylphosphino‐substituted alkynes undergo a 1, 1‐carboboration reaction with tris(pentafluorophenyl)borane to yield 2‐diarylphosphino‐substituted alkenylboranes. These unsaturated systems show a P/B interaction. Nevertheless, they feature a limited frustrated Lewis pair (FLP) reactivity. Four such unsaturated vicinal FLPs were shown to react with benzaldehyde to give the respective six‐membered heterocyclic P/B FLP 1, 2‐addition products, which were characterized by X‐ray diffraction.
