    Description / Table of Contents: High Pressure Experiments, XIII. Reaction of tert-Butyl Isonitrile and of Toluene with Bicyclo[2.2.1]heptene (Norbornene) at High PressureAt pressure of about 10 kbar tert-butyl isonitrile reacts with bicyclo[2.2.1]heptene (norbornene) in low yield to give many products of which addition compounds 2 - 11 were identified. With pure toluene exo-2-benzylbicyclo[2.2.1]heptane (10) was found. With oxygen containing toluene also exo-2,3-epoxybicyclo[2.2.1]heptane (2) was isolated. The structure of methanopyrroloindole 6 is confirmed by an X-ray structure analysis.
    Notes: Unter einem Druck von etwa 10 kbar verbindet sich tert-Butylisonitril mit Bicyclo-[2.2.1]hepten (Norbornen) in geringer Ausbeute zu mehreren Produkten, von denen die Verbindungen 2 - 11 aufgeklärt werden konnten. Mit reinem Toluol entsteht in 41proz. Ausbeute exo-2-Benzylbicyclo[2.2.1]heptan (10). Mit sauerstoffhaltigem Toluol wird auch exo-2,3-Epoxybicyclo[2.2.1]heptan (2) erhalten. Von Methanopyrroloindol 6 wurde eine Röntgenstrukturanalyse durchgeführt.

    Notes: Unexpected Behaviour of 2-Bromoethyl 4-Hydroxybenzoate with Sodium HydroxideWhereas 2-bromoethyl benzoate hydrolyzes quickly with sodium hydroxide to yield benzoic acid, 2-bromoethyl 4-hydroxybenzoate (1) with equimolar amounts of sodium hydroxide gives quantitatively 2-hydroxyethyl 4-hydroxybenzoate (6). It is proved with deuterated compounds that this reaction proceeds with internal C=O alkylation via the intermediate 5.

    Description / Table of Contents: High Pressure Experiments, XII. - Application of High Pressure on Wittig Reactions with Resonance Stabilized YlidesAt pressures of about 10 kbar the reaction of aldehydes with resonance stabilized ylides gets strongly accelerated. The yield of the trans-olefin is increased.
    Notes: Unter Druck von etwa 10 kbar wird die Reaktion von Aldehyden mit resonanzstabilisierten Yliden stark beschleunigt. Dabei wird der Anteil des trans-Olefins erhöht.
