    Description / Table of Contents: Thermal Behaviour of AllyloxycarbenesDiallyloxycarbene (2e) decomposes into allyl radicals and carbon dioxide at 250° in the vapor phase. Methoxy(allyloxy)carbene (2d) suffers a similar decomposition but in addition rearranges by a methyl- as well as an allyl-shift. At least the latter rearrangement involves free radicals as labelling experiments suggest.
    Notes: Das Diallyloxy-carben (2e) zerfällt bei 250° in der Gasphase in Kohlendioxid und Allyl-Radikale. Das Methoxy-allyloxy-carben (2d) erleidet neben einem gleichartigen Zerfall eine Umlagerung sowohl unter Methyl- als auch Allyl-Verschiebung. Zumindest die Allyl-Verschiebung verläuft über freie Radikale, wie Markierungsversuche wahrscheinlich machen.

    Synthesis of Isomerically Pure Organodihydrofullerenes (1993)

    Notes: Controlled two-step nucleophilic hydroalkylations, hydroar-ylations as well as hydrostannylations of fullerene-60 (1) and fullerene-70 (2) lead to defined organodihydrofullerenes C60HR and C70HR. NMR investigations show that only one isomer of each organodihydrofullerene with Cs symmetry is formed. In all cases the addition takes place at a double bond separating two six-membered rings of the fullerene core. In this way a variety of organodihydrofullerenes also carrying functional groups have been synthesized.

    Darstellung von Enolsulfonsäureestern aus Trimethylsilylenolethern  -  Synthetische Konsequenz eines bemerkenswerten Kationeneffekts (1982)

    Description / Table of Contents: Preparation of Vinylsulfonates from Trimethylsilyl Enol Ethers  -  Synthetic Consequences of a Remarkable Cation EffectThe C/O-selectivity observed in the sulfonylation of the enolate ion 5 with benzenesulfonyl fluoride depends strongly on the nature of the gegenion. Li⊕ yields the β-oxosulfone 3 by C-sulfonylation exclusively. The fraction of O-Sulfonylation is increased with the size of the cation, yielding the vinylsulfonates 6b exclusively in the presence of Cs⊕ or quaternary ammonium ions. From this behaviour a regio- and stereoselective synthesis of vinylsulfonates is developed starting from the corresponding trimethylsilyl enol ethers.
    Notes: Die C/O-Selektivität der Sulfonylierung des Enolat-Ions 5 mit Benzolsulfonylfluorid zeigt einen starken Einfluß des Gegenions. Während mit Li⊕ ausschließlich C-Sulfonylierung zum β-Oxosulfon 3 erfolgt, wächst mit der Größe des Kations der Anteil an O-Sulfonylierung, bis mit Cs⊕ oder quartären Ammonium-Ionen ausschließlich Enolsulfonsäureester 6b entstehen. Dieses Verhalten wird für eine regio- und stereoselektive Synthese von Enolsulfonsäureestern aus den entsprechenden Trimethylsilyl-enolethern genutzt.

    Synthesis and Electrochemistry of Diels-Alder Adducts of [60] Fullerene with a Phthalocyanine and a Hemiporphyrazine (1997)

    Notes: The synthesis of a new Diels-Alder adduct 7 of [60]fullerene and a phthalocyaninenickel compound containing a longer spacer than the originally reported Diels-Alder adduct 1 is described. The bisenophilic hemiporphyrazinenickel compound 11 reacts with [60]fullerene to form a Diels-Alder adduct 12 containing two fullerene units. Spectroelectrochemical investigations of 7 and 12 reveal multiple reductions, which are attributed to the corresponding subunits of the molecules. In contrast to 1, the election acceptor properties of the [60]fullerene unit in both molecules have no influence on the electronic properties of the phthalocyanine and hemiporphyrazine, respectively.

    Notes: Monomeric and Bridged Oligomeric (Tetrasulfophthalocyaninato)iron(II) Complexes with Isocyanides and N-Donors as Axial Ligands(Tetrasulfophthalocyaninato)iron(II) (TsPcFe) (1) is treated with the isocyanides tert-butyl isocyanide (tBuNC), 1,4-diisocyanobenzene (dib), 2,3,5,6-tetramethyl-1,4-diisocyanobenzene (me4dib), and 4-isocyano-3,5-dimethylpyridine (me2pyNC), and also with pyrazine (pyz) leading to bisaxially coordinated monomers TsPcFe(L)2 (L=tBuNC, dib, me4dib) and the bridged oligomers [TsPcFe(L)]n (L=dib, me4dib, me2pyNC, and pyz). All these complexes are soluble in methanol or water. The spectroscopic properties of the complexes are described, and the average chain lengths of the bridged oligomers are determined by 1H-NMR spectroscopy. The bridged stacked systems exhibit semiconducting properties with and without iodine doping.
