    Description / Table of Contents: Reactions of Oxygen- and Sulfur-Heterocycles with Sodium and Dichloro(diisopropylamino)boraneThiophene reacts with sodium and dichloro(diisopropylamino)borane to give 2,4-Bis-(diisopropylamino)-1,3,2,4-dithiadiboretane (a). In the reactions of dibenzothiophene, dibenzofurane, and xanthene, resp., with sodium and dichloro(diisopropylamino)borane one side of the hetero-bridge is split. Thus one obtains the amino(phenylthio)borane 1 and the amino(phenoxy)- boranes 2 and 3. The compounds are characterized analytically and spectroscopically (MS; NMR: 1H, 11B, 13C).
    Notes: Thiophen reagiert mit Natrium und Dichlor(diisopropylamino)-boran zum 2,4-Bis(diisopropylamino)-1,3,2,4-dithiadiboretan (a). Bei der Umsetzung von Dibenzothiophen, Dibenzofuran bzw. Xanthen mit Na und Dichlor(diisopropylamino)boran wird die Heterobrücke jeweils auf einer Seite gespalten. Man erhält so das Amino(phenylthio)boran 1 und die Amino(phenoxy)borane 2 und 3. Die Verbindungen werden analytisch und spektroskopisch (MS; NMR: 1H, 11B, 13C) charakterisiert.
