    Notes: Synthesis and Characterization of Substituted Nickel HemiporphyrazinesThe butoxy-substituted (hemiporphyrazinato)nickel compounds (C4H9O)2HpNi (7), (C4H9O)4HpNi (11), and (C4H9O)6HpNi (12) are prepared from isoindolenine 4 or 4,7-dibutoxy-1,3-dihydro-1,3-diiminoisoindole (8), 2,6-diaminopyridines and nickel acetate. The complexes 7, 11, and 12 are soluble in common organic solvents and were characterized by 1H-and 13C-NMR spectroscopy.

    Nickel Hemiporphyrazines as Bisdienes and Bisdienophiles: Synthesis and Characterization (1996)
    Weinheim : Wiley-Blackwell
    Berichte der deutschen chemischen Gesellschaft 129 (1996), S. 237-242 
    Details
    ISSN: 0009-2940
    Keywords: Hemiporphyrazines ; Macrocyclic bisdienes and bisdienophiles ; Nickel complexes ; Chemistry ; Inorganic Chemistry
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: The bisdienophilic (hemiporphyrazinato)nickel complexes 1a-d bearing various alkoxy groups were synthesized from diiminoisoindoles 9a-d, diaminopyridines 10a, d, and nickel acetate. Reaction of 1a-d with an excess of pentaene 3 delivered the macrocyclic bisdienes 2a-d. The hemiporphyrezines were characterized by 1H- and 13C-NMR spectroscopy. The NMR spectra of the 1,6,16,21-tetrabutoxy-substituted compounds 1b and 2b are discussed with respect to the presence of syn/anti isomers.

    Synthese und Charakterisierung neuer Hemiporphyrazinato-Nickelkomplexe (1995)
    Weinheim : Wiley-Blackwell
    Berichte der deutschen chemischen Gesellschaft 128 (1995), S. 417-421 
    Details
    ISSN: 0009-2940
    Keywords: Hemiporphyrazines ; Heminaphthoporphyrazines ; Nickel complexes ; Chemistry ; Inorganic Chemistry
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: Synthesis and Characterization of New Hemiporphyrazinato Nickel ComplexesThe new substituted (hemiporphyrazinato)nickel complexes [HpNi] 3-9 and 11-14, the (heminaphthoporphyrazinato)-nickel complexes 15-19 [HnpNi], and the hemianthraceno-phorphyrazine complex [HapNi] 20 are prepared from isoin-dolenines 1a-e and 10a-d, diaminopyridines 2a-e and nickel acetate. The compounds were characterized by 1H- and 13C-NMR spectroscopy. The 1H-NMR spectrum of the mixture of the 3,18/3,19-substituted (C2v/C2h) complexes is discussed.
