Abstract

Abstract : The reaction of the intramolecular frustrated Lewis pair (FLP) t Bu2 PCH2 BPh2 with the amine‐boranes NH3 · BH3 and Me2 NH· 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 FLP. The sterically more demanding t Bu2 PCH2 BMes2 does not form such a five‐membered heterocycle when reacted with Me2 NH· BH3 and its H2 adduct liberates dihydrogen at elevated temperatures, promoting the metal‐free catalytic dehydrogenation of amine‐boranes.
