An amine–ammonium salt equilibration–metathesis sequence provides high-purity amine–boranes in excellent yields from sodium borohydride in refluxing reagent-grade tetrahydrofuran in an open flask.

them to hypergols or decreases their ignitiondelays (IDs) multifold (with white fuming nitric acid as the oxidant). With consistentlylow IDs, amine–boranes represent a class of compounds that can be promising alternatives to toxic hydrazine and its derivatives as propellants. A structure–hypergolicity relationship study reveals the necessary features for the low ID.
