    Description / Table of Contents: Addition of Diborontetrahalides to Unsaturated HydrocarbonsB2Cl4 and B2F4 add on the C = C-bond of methylenecyclopropane or vinylcyclopropane forming the diboryl compounds 3 and 5 respectively, C—C-bonds of the cyclopropane rings are not cleaved even using an excess of B2Cl4. The properties of the new compounds and their spectroscopic data are listed.
    Notes: B2Cl4 und B2F4 addieren sich an die C = C-Bindung von Methylencyclopropan bzw. Vinylcyclopropan unter Bildung der Diborylverbindungen 3 bzw. 5. C—C-Bindungen der Cyclopropanringe werden auch bei einem Überschuß von B2Cl4 nicht gespalten. Die Eigenschaften der neuen Verbindungen und ihre spektroskopischen Daten sind aufgeführt.

    Description / Table of Contents: Reactions of Chloroboranes with Bifunctional BasesReaction of trichloroborane with 2-(trimethylsilylamino)pyridine (1b) and 2-(trimethylsilyloxy)-pyridine (2b) yields the dimeric dichloro(2-pyridylamino)borane 4 and the dimeric dichloro-(2-pyridyloxy)borane 5, respectively. In a 1:2 molar ratio tetrachlorodiborane(4) and 2b react to form the bicyclus 6, while equimolar amounts react in a complex way.
    Notes: Aus Trichlorboran erhält man mit 2-(Trimethylsilylamino)pyridin (1b) und 2-(Trimethylsilyloxy)-pyridin (2b) das dimere Dichlor(2-pyridylamino)boran 4 bzw. das dimere Dichlor(2-pyridyloxy)-boran 5. Tetrachlordiboran(4) und 2b setzen sich bei einem Molverhältnis von 1:2 zum Bicyclus 6 um, während äquimolare Mengen unübersichtlich reagieren.
