 Title    Reaktionen mit Kaliumsuperoxid 3 [1] Über den Mechanismus der Ketonspaltung durch K0 2 Reactions with Potassium Superoxide 3 [1] On the Mechanism of the Cleavage of Ketones by K0 2  
 Abstract    Some experiments on the mechanism of the oxidative cleavage of ketones are presented. The results show that the general mechanism of base catalysed autoxidation is operating.

 Title    Molekulare Reaktionen in kalten Methan-Wasser-Plasmen und die Wirkung von UV-Bestrahlung Molecular Reactions in Cold Methane-Water Plasma and the Effect of UV Irradiation  
 Abstract    After passage of methane-water mixtures through the state of a cold plasma, numerous products were identified, especially aldehydes, ketones, alcohols and acids. Their concen-tration was dependent on the methane/water ratio. Irradiation with UV light during or after the process gave transformations of the above compounds to more complex combi-nations. For the formation of ketones, aldehydes, alcohols and acids a detailed mechanism is proposed.

 Abstract    The significance of pheromones in olfactory communication in mammals, and the possibility of using synthetic pheromones to influence the behaviour of problem animals, are briefly discussed. The isolation, identification and synthesis of the principal volatile component contained in the pedal gland exudate of the bontebok, Damaliscus dorcas dorcas, viz. (Z)-5-undecen-2-one, are re­ ported. Some of the other major constituents of the secretion have been identified as 2-heptanone, 2 -nonanone, 2 -undecanone and 2,5-undecanedione.
