The reaction of the intramolecular frustratedLewispair (FLP) tBu2PCH2BPh2 with the amine-boranes NH3·BH3 and Me2NH·BH3 leads to the formation of the corresponding FLP-H2 adducts as well as novel five-membered heterocycles that result from capturing the in situ formed amino-borane by a second equivalent of
An azaborine bearing two dimesitylboryl groups on its periphery showed very strong light absorption and moderate photo-luminescence emission; the reaction of the title compound with fluoride ion resulted in multi-step fluoride ion complexation on the boron atoms of the dimesitylboryl groups, producing mono- and bisfluoroborates.
