    Notes: Abstract Diaza-18-crown-6 (1,4,10,13-tetraoxa-7,16-diaza-cyclo-octadecane) selectively precipitates as a 1,4-dihydroxybenzene-complex from a mixture of isomeric phenols and as a 2,6-dihydroxynapthalene-complex from mixtures of isomeric diols. These selective precipitations are discussed in terms of structure and solubility of the host-guest complexes and phenol acidity. The crystal structures of diaza-18-crown-6 with guestsp-nitrophenol (2: 1), 2,4-dinitroaniline (2: 1), 5,5-diethylbarbituric acid (2: 1), salicylaldoxime (2: 1) and 1,4-dihydroxybut-2-yne (1: 1) are reported.

    Homocalixarenes and homocalixpyridines (1994)
    Springer
    Journal of inclusion phenomena and macrocyclic chemistry 19 (1994), S. 111-135 
    Details
    ISSN: 1573-1111
    Keywords: Phane syntheses ; all-homocalixarenes ; all-homocalixpyridines ; host tailoring ; large functionalized cavities ; host properties ; liquid-liquid-extraction experiments ; crystal structures

    Topics: Chemistry and Pharmacology
    Notes: Abstract A new type of host is introduced:all-homocalixarenes. Phane syntheses leading to molecules which may be termed, in the most general sense, homocalixarenes, are outlined in a brief overview. The design, synthesis, conformations and host properties ofall-homocalixarenes andall-homocalixpyridines are described in detail.
