    Description / Table of Contents: Sugar-Siloxanes, II Synthesis of some Silicium-containing Sugar DerivativesSome sugar-silicium compounds have been synthesized by addition of methyldiethoxysilane to unsaturated monosaccharide derivatives. Among others the hitherto unknown compounds 6.7-Dideoxy-1.2;3.4-di-O-isopropylidene-α-D-galacto-hept-6-enopyranose (2) with a straight carbon chain and 3-O-acetyl-3-C-ethynyl-1.2;5.6-di-O-isopropylidene-α-D-allofuranose (8b) as well as ethynediyl-3-C.3′-C-bis(3-O-acetyl-1.2;5.6-di-O-isopropylidene-α-D-allofuranose) (9b) with branched carbon chains were used as starting materials. No addition, probably due to steric hindrance, was observed with 9b.
    Notes: Eine Reihe von Zucker-Siliciumverbindungen wurde durch Addition von Methyldiäthoxysilan an ungesättigte Monosaccharidderivate dargestellt. Als Ausgangsprodukte dienten unter anderen die bisher unbekannten Verbindungen 6.7-Didesoxy-1.2;3.4-di-O-isopropyliden-α-D-galakto-hept-6-enopyranose (2) mit unverzweigtem sowie 3-O-Acetyl-3-C-äthinyl-1.2;5.6-di-O-isopropyliden-α-D-allofuranose (8b) und Äthindiyl-3-C-.3′-C-bis-[3-O-acetyl-1.2;5.6-di-O-isopropyliden-α-D-allofuranose] (9b) mit verzweigtem Kohlenstoffgerüst. An die Verbindung 9b ließ sich, offenbar aus sterischen Gründen, kein Silan addieren.

    Description / Table of Contents: A new Method for preparing pure Bromine(III) fluoride. Bromine(III) fluoride is formed by the reaction of fluorine with elemental bromine in CCl3F at about -40°C as a very pure solid.
    Notes: Bromtrifluorid läßt sich in sehr reiner Form durch Direktfluorierung von elementarem Brom in CCl3F bei etwa -40°C darstellen und kann ohne weitere Reinigung für präparative Zwecke benutzt werden.
