Zusammenfassung Boron trifluoride reacts at 0 with silylamines of the type Me 3 Si-NHR (R= Me, Et, Pr, i-Pr, Bu, t-Bu, Ph) to give adducts which are not stable at room temperature. Their decomposition proceeds with the elimination of Me 3 SiF and leads to the formation of aminoboranes having the general composition RNH-BF 2; these are unstable, too, and decompose further to give the corresponding primary amine/boron trifluoride adducts and ...
