Diborylamines of the types (R2B)2NH and (R2B)2NR′ (R = CH3, C2H5, C3H7, C4H9;R′ = CH3) are obtained (a) from dialkylhaloboranes and disilazanes, (b) from dialkylhaloboranes and N-metalated aminoboranes, and (c) by aminolysis of dialkyl(mthylthio)boranes. They are thermodynamically unstable with respect to a decomposition into trialkylboranes and borazine derivatives; their decomposition is catalysed
