摘要：
The complexation of dibromo-fluorenylborane (FluH-BBr2) with bulky bis(2,6-diisopropylphenyl)imidazol-2-ylidene (IPr) afforded N-heterocyclic carbene (NHC) borane adduct 1, which could be subsequently dehydrobrominated by smaller 1,3-diisopropyl-4,5-dimethylimidazol-2-ylidene (IPr2Me2) to give the alkylideneborane-NHC complex 2. Species 2 readily binds with potassium ion to form a potassium alkylideneborane complex 3 through exclusive cation-pi interactions.
