    Notes: Synthesis of 1.7-DiazaperyleneThe hitherto unknown 1,7-Diazaperylene (2) has been prepared in a five-step synthesis from 1,5-diaminoanthraquinone (3) by a Meerwein arylation reaction. Applications as a fluorescent dye are discussed.

    Notes: Synthesis of Nonsymmetrically Substituted Perylene Fluorescent DyesA general method for the preparation of perylene-3,4:9,10-tetracarboxdiimides 1 with two different substituents at the nitrogen atoms is described: The easily prepared symmetrical tetracarboxdiimides 1 (R1=R2) are transformed into carboxdiimide anhydrides 2 and condensed with primary amines to the corresponding tetracarboxdiimides 1 (R1 ≢ R2). Applications as fluorescent tracers in biochemistry and polymer chemistry are discussed.

    Notes: Synthesis of Highly Pure Rubicene and Rubicene DerivativesA simple one-step synthesis of highly pure rubicene (2) from fluorenone (1) and magnesium with 24% yield is described and compared with other preparation procedures. Mono- and disubstituted rubicene derivatives are prepared by electrophilic aromatic substitution.

    Sextettumlagerungen als Solvens-Polaritätssonde (1990)
    Weinheim : Wiley-Blackwell
    Berichte der deutschen chemischen Gesellschaft 123 (1990), S. 407-409 
    Details
    ISSN: 0009-2940
    Keywords: Solvent polarity / Solvent effects / Beckmann rearrangement / Solvent polarity scales, empirical ; Chemistry ; Inorganic Chemistry
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: Sextett Rearrangements as Solvent Polarity ProbesThe rate constant of the Chapman variant of the Beckmann rearrangement is used as a solvent polarity probe and is mainly influenced by the polarizability of the solvent. Analogies to SN reaction are discussed.
