    Notes: Abstract The odour of the formerly unknown compounds benzyldimethylmethoxysilane2 a (flower-honey like with a minty component; intensity middle), bis(benzyl)tetramethyldisiloxane4 a (flowerlike; very weak) and bis(benzyl)tetramethyldigermoxane9 (almond-soapy like; relatively strong) was registered and compared with related compounds (for example benzyldimethylmethoxymethane5 a, camphor-radish like). Information is given on preparation and analytical and structural investigation of several methoxysilanes and disioxanes with benzyl and phenethyl groups (compare equations and experimental part).

    Notes: Kinetic Investigation of the Platinum-catalysed Hydrosilylation of Vinylsiloxanes with HydrogensiloxanesA kinetic investigation of the platinum-catalysed hydrosilylation of monofunctional oligomeric vinylsiloxanes by monofunctional oligomeric hydrogensiloxanes was performed under stoichiometric conditions with use of quantitative 1H-NMR spectrometry. The reaction rate up to 50% conversion can be expressed by v=k [Pt]. During further hydrosilylation the kinetic changed to second order. No induction period was observed. A hydrogensiloxane with a dimethylsilyl end group gives much higher rates than a siloxane with a methylsiloxy group. The main reactions of all hydrosilylations, determined by GC-MS and 29Si-NMR, are β-additions. Less then 5% α-products are obtained.

    Description / Table of Contents: Sila Perfumes, I. Sila Analogues of Tertiary Carbinols as PerfumesSilanols RR′R″SiOH 7 which are analog to carbinols 1 with strong odour in the region of flowery notes (lily of the valley-hyacinth-rose) were prepared via reaction steps (3) and partially unknown intermediates 6. Sila perfumes 7 are similar in intensity and spectrum of odour to 1 but a shift from lily of the valley towards hyacinth notes is generally observed.
    Notes: Es wurden Silanole RR′R″SiOH 7 dargestellt, die Carbinolen RR′R″COH 1 (R = CH3, R′ = CH3, CH=CH2, C2H5, R″ = CH2C6H5, CH2CH2C6H5) mit starker Duftwirkung im Bereich blumiger Noten (Maiglöckchen-Hyazinthe-Rose) analog waren. Ihr Syntheseweg verläuft über die Reaktionsschritte (3) mit teilweise bisher unbekannten Zwischenstufen 6. Die Sila-Riechstoffe 7 sind in Intensität und Duftbereich den Carbinolen 1 ähnlich, doch ist allgemein eine Verschiebung der Duftnote von Maiglöckchen zu Hyazinthe zu beobachten.

    Description / Table of Contents: Sila-Perfumes, 21)  -  Sila-LinaloolMethyl(4-methyl-3-pentenyl)vinylsilanol (2), the sila derivative of the naturally occuring linalool (1), could be prepared from dichloro(methyl)vinylsilane following the outlined method. The intensity of odour of 2 is similar to that of 1 but its note is somewhat shifted from the fragrance of lilies of the valley to that of hyacinths. Furthermore, a forerunner of 2 (chlorosilane 4), a reaction product of 2 (disiloxane 6), and some compounds from parallel investigations, e. g. the chlorosilane 3 or the morpholino silane 5, are described.
    Notes: Methyl(4-methyl-3-pentenyl)vinylsilanol (2), das Siladerivat des natürlich vorkommenden Linalools (1), konnte ausgehend von Dichlor(methyl)vinylsilan auf dem skizzierten Reaktionsweg dargestellt werden. Seine Geruchsintensität ist der von 1 gleich, seine Geruchsnote vom Maiglöckchenduft des Linalools etwas zum Hyazinthenduft hin verschoben. Es werden eine Vorstufe von 2 (Chlorsilan 4), ein Reaktionsprodukt von 2 (Disiloxan 6) sowie in Paralleluntersuchungen auftretende Verbindungen wie das Chlorsilan 3 oder das Morpholinosilan 5 beschrieben.

    Description / Table of Contents: Sila- Perfumes, 5 Sila- Terpineol and Related CompoundsDimethyl(4-methyl-3-cyclohexenyl)silanol (6), the sila derivative of α-terpineol - a component of many ethereal oils with the fragrance of lilac - could be synthesized according to Scheme 1. The intensity of the fragrance of 6 is comparable with the natural product, but its spectrum somewhat shifted to the odour of the lily of the valley. From forerunners in the synthesis of 6 the sila derivative 4 of γ-terpinene (herbal/terpine-like) and the sila derivative 5 of carvomenthene (lemonene-like fragrance) could be obtained by reduction; both are similar in intensity and quality of odour to the related carbon compounds.
    Notes: Dimethyl(4-methyl-3-cyclohexenyl)silanol (6), das Sila-Derivat des in einigen ätherischen Ölen vorkommenden und fliederartig duftenden α-Terpineols, konnte auf dem in Schema 1 skizzierten Reaktionsweg dargestellt werden. Es ist in der Geruchsintensität diesem gleich, doch verschiebt sich das Duftspektrum etwas zum Maiglöckchengeruch hin. Aus Vorstufen der Synthese konnten das Sila-Derivat 4 des γ-Terpinens (krautig-terpinig) und das Sila-Derivat 5 des Carvomenthens (limonenartiger Duft) synthetisiert werden; beide besitzen nahezu gleiche Geruchsqualität und -intensität wie die entsprecheden Kohlenstoffverbindngen.
