    Description / Table of Contents: Contributions to the Chemistry of Boron, 134. Adducts of (Dimethylamino)boranes with Aluminium and Gallium Halides2)The (dimethylamino)boranes (CH3)2BN(CH3)2 (1) and RB[N(CH3)2]2 (2, 3) form 1 : 1 adducts 1a - c and 2a, b, 3a, b with AlCl3, AlBr3, and GaCl3, respectively, in contrast to B[N(CH3)2]3 (4) which reacts with GaCl3 to produce a 1:2 adduct 4a. NMR and IR data are in accord with the presence of a simple N - Al or N - Ga coordinative bound for the first two classes of compounds. However, 4a is to be regarded as a tris(dimethylamino)borane-dichlorogallium(1+) tetrachlorogallate containing a bidentate aminoborane component.
    Notes: Die (Dimethylamino)borane (CH3)2BN(CH3)2 (1) und RB[N(CH3)2]2 (2, 3) bilden mit AlCl3, AlBr3 und GaCl3 1 : 1-Addukte 1a - c und 2a, b, 3a, b, während B[N(CH3)2]3 (4) mit GaCl3 zu einem 1:2-Addukt 4a reagiert. NMR- und IR-Daten weisen den beiden erstgenannten Verbindungstypen Strukturen mit einer einfachen N - Al- bzw. N - Ga-Koordination zu. Im Gegensatz dazu ist 4a als Tris(dimethylamino)boran-dichlorgallium(1+)-tetrachlorogallat aufzufassen, in der die Aminoboran-Komponente als zweizähniger Ligand wirkt.
