    Notes: 1, 4-Dimethylcyclohex-3-enyl methyl ketone (1) has been isolated from the oil of Juniperus communis L. (fruit). This is the first reported occurrence of this skeleton in nature. A curious effect on the NMR.-spectrum of the compound (1) by the shift agent, Eu(fod)3, is described.

    Notes: A 1, 6-addition of sulfonyl chloride isocyanate to 5, 7-dimethyl-8-methylidene-tricyclo[3.2.1.02,7]oct-3-en-6-one (1) produced the new tricyclic skeleton of 4a, 6-dimethyl-2, 5-dioxo-2, 3, 4a, 5, 6, 8a-hexahydro-1H-6, 4-methenoquinoline-1-sulfonyl chloride (2). The structure of the new aza-tricyclic species has been elucidated by X-ray analysis.

    Notes: It has been shown that the reaction of the title ketone with phosphorous pentachloride leads to regiospecific chlorine transfer to the diene moiety of the molecule, leaving the carbonyl function intact. Attempted acetalization with ethylene glycol did not give the dioxolane but rather 1,2,3,4,5-pentamethylcyclopenta-1, 3-diene in quantitative yield. An independent synthesis of this hydrocarbon, previously available only by lengthy multistep synthesis, has also been described. The only normal carbonyl reaction of the permethyl-acetyl-cyclopentadiene observed was the reduction by metal hydrides.

    Notes: 2-Aminopyridin-N-oxid und die entsprechenden Chinolin- und Isochinolin-Derivate geben beim Diazotieren mit Natriumnitrit in Gegenwart von Tetrafluoroborwasserstoffsäure 1,2,3,5-Oxatriazolium-tetrafluoroborate, die als cyclische Diazoniumverbindungen spontan mit alkalischer β-Naphthol-Lösung kuppeln. Durch IR-, UV- und NMR-Untersuchungen und Vergleich mit dem isomeren Diazoniumsalz des 4-Aminopyridin-N-oxids wird die Struktur dieser neuartigen heterocyclischen Verbindungen gesichert.

    Description / Table of Contents: (1,2-Dihaloethylene)tetracarbonyliron Complexes: Preparation, IR- and NMR-SpectraThe tetracarbonyliron complexes of cis- and trans-1-bromo-2-fluoroethylene, cis- and trans-1,2-dichloroethylene, cis- and trans-1,2-dibromoethylene, trans-1-bromo-2-iodoethylene, trans-1,2-diiodoethylene, vinyl bromide and 1,1-dichloroethylene have been prepared by reaction of the corresponding olefins with Fe2(CO)9. According to IR investigation all compounds have trigonal bipyramidal configuration, the olefin occupying an equatorial position. There exists a systematic correspondence of the force and interaction constants, and the symmetry and the donor and acceptor properties of the olefins, which is also reflected in the NMR spectra.
    Notes: Die Tetracarbonyleisen-Komplexe von cis- und trans-1-Brom-2-fluoräthylen, cis- und trans-1,2-Dichloräthylen, cis- und trans-1,2-Dibromäthylen, trans-1-Brom-2-jodäthylen, trans-1,2-Dijodäthylen, Vinylbromid und 1,1-Dichloräthylen wurden durch Umsetzung der entsprechenden Olefine mit Fe2(CO)9 dargestellt. Sämtliche Verbindungen sind nach IR-Untersuchungen trigonal-bipyramidal konfiguriert, das Olefin besetzt eine äquatoriale Position. Zwischen den Kraft- und Wechselwirkungskonstanten sowie der Symmetrie und den Donor- und Akzeptoreigenschaften der Olefine bestehen systematische Zusammenhänge, die sich auch n den NMR-Spektren ausdrücken.

    Notes: In studies of various polymers in the solid state by pulsed and wide-line NMR, a relationship between the spin-lattice relaxation time and the fraction of mobile protons in the polymer sample was observed. This effect has been used to determine the degree of polymerization of a series of fumaronitrile homopolymers. The technique should have wide applicability in the direct determination of the number-average molecular weight M̄n, especially for polymers that may be insoluble and/or infusible though not crosslinked.

    Description / Table of Contents: 1,3-Butadienylsulfonium Salts, II1)  -  Reaction of trans-(1,3-Butadienyl)dimethylsulfonium Halides with Bases**)Some reactions of butadienylsulfonium salts with alkali hydroxide, thiophenolate, and alkoxides are described. With catalytic amounts of alkoxide in alcoholic solution the dienylsulfonium salts 1a, b yield (2,4-dialkoxybutyl)sulfonium salts 7 and/or (alkoxybutenyl)-sulfonium salts 4 and 6. At high alkoxide concentration the main products are substituted butenyl sulfides 9, formed by [2,3]-sigmatropic rearrangement of the 4-ylides. Under the same conditions (2,3-dimethyl-1,3-butadienyl)dimethylsulfonium bromide (1c) rearranges to 2-methyl-3-methylene-5-methylthio-1-pentene (16).
    Notes: Einige Reaktionen der Butadienylsulfoniumsalze 1 mit Alkalihydroxid, Thiophenolat und Alkoholaten werden beschrieben. Mit katalytischen Mengen Alkoholat ergeben die Dienylsulfoniumsalze 1a, b in alkoholischer lösung die (2,4-Dialkoxybutyl)sulfoniumsalze 7 und/oder die (Alkoxybutenyl)sulfoniumsalze 4 und 6. Bei hohen Alkoholatkonzentrationen werden durch [2,3]-sigmatrope Umlagerung der 4-Ylide hauptsächlich die substituierten Butenylsulfide 9 gebildet. (2,3-Dimethyl-1,3-butadienyl)dimethylsulfoniumbromid (1c) liefert unter diesen Bedingungen 2-Methyl-3-methylen-5-methylthio-1-penten (16).
