    Notes: Eine neue Darstellung von Dehydrocamphenilon und CamphenilonBenzilsäureumlagerung von Dehydrocarbocamphenilon (4) ergibt die α-Hydroxysäure 5, welche mit Bleitetraacetat oxidativ zu Dehydrocamphenilon (2) decarboxyliert wird. Die gleiche Reaktionsfolge führt von Carbocamphenilon (9) zu Camphenilon (3).

    Notes: Die ungesättigte Ketosäure II konnte aus dem Isopentenylchlorid III über die Grignard-Verbindung mit Oxalester in 10-proz. Ausbeute erhalten werden. Ihr Strukturbeweis wurde durch IR- und Protonenresonanzspektroskopie geführt. Das Phenythydrazon geht bei der katalytischen Hydrierung in eine einheitliche ninhydrin-positive Verbindung über, die wohl ein β-Methyl-leucin ist.Die Addition substituierter Cyclopentadiene an Äthylen zu einer Reihe alkylsubstituierter Bicyclo-[1.2.2]-heptene, deren wichtigster Vertreter das Santen ist.

    Notes: Metal phthalocyanines (M = Cu, Ni, Co) 3-5 bearing four 16-membered diazadithia macrocycles at the peripheral positions were prepared. Detosylation with concentrated sulfuric acid afforded products containing both sulfonated groups on the aromatic rings of the macrocyclic substituents which are excellently soluble in water and donor sites for binding four CuII ions to give a pentanuclear complex.

    Description / Table of Contents: New silylamine esters (m. p.' s 〈 150°C) have been prepared by condensation of excess diorganodichlorosilanes with diphenols in the presence of amine catalysts, followed by interacting the terminal chloro groups with ammonia and primary amines, respectively. Si-phenylsilazane esters with free terminal amino groups are formed as silylamines, whereas silazane esters with alkyl-substituted silicon react to yield polysilazane-polysilicic acid esters.
    Notes: Neue veresterte Silylamine mit Fließpunkten unter 150°C wurden hergestellt durch Kondensation von überschüssigen Diorganodichlorsilanen mit Diphenolen in Gegenwart von Aminkatalysatoren. Die Chlorendgruppen werden anschließend mit Ammoniak bzw. primären Aminen umgesetzt. Es wurde gefunden, daß Si-phenylsilazanester mit freien Aminoendgruppen als Silylamine anfallen, dagegen bilden Silazanester mit alkyl-substituiertem Silicium Polysilazanpolykieselsäureester.

    Description / Table of Contents: A simple method for preparing halogenphenylesters of phosphoric, phenylphosphonic and phosphorous acid from the respective acid chlorides and phenols in the presence of various nitrogen-containing catalysts is described. Contrary to other methods, these reactions give high yields, despite of steric hindrance.
    Notes: Eine einfache Methode zur Herstellung von Halogenphenylestern der Phosphorsäure Phenylphosphorsäure und phosphorigen Säure aus deren Säurechloriden und Phenolen in Gegenwart von verschieden stickstoffhaltigen Katalysatoren wird beschrieben. Die Reaktion führt trotz sterischer Hinderung im Gegensatz zu anderen Verfahren zu sehr hohen Ausbeuten.

    Description: Stratospheric ozone and aerosol distributions were measured across the wintertime Arctic vortex from January to March 1992 with an airborne lidar system as part of the 1992 Airborne Arctic Stratospheric Expedition (AASE II). Aerosols from the Mount Pinatubo eruption were found outside and inside the vortex with distinctly different distributions that clearly identified the dynamics of the vortex. Changes in aerosols inside the vortex indicated advection of air from outside to inside the vortex below 16 kilometers. No polar stratospheric clouds were observed and no evidence was found for frozen volcanic aerosols inside the vortex. Between January and March, ozone depletion was observed inside the vortex from 14 to 20 kilometers with a maximum average loss of about 23 percent near 18 kilometers.

    Description: Airborne differential absorption lidar and in situ data obtained during the April 20, 1984 flight experiment conducted over Nevada and California are analyzed. The O3 and aerosols profiles and in situ measurements reveal a 2.0-km-deep layer (with high O3 concentrations and enhanced aerosol backscattering) and a correlation of 0.8 between O3 and aerosol backscatter (with both values decreasing about 25 percent along the central axis of the fold). It is observed that the cold boundary of the fold has weaker gradients, larger-scale undulations, and more irregularity than the warm boundary. The potential vorticity distribution along the flight path was derived from radiosonde data. A positive correlation between the O3 mixing ratio and the potential vorticity values in the fold is detected; the average ratio between O3 and potential vorticity is 50.2 ppbv/10 to the -5th sq cm deg per g s.
