    Description / Table of Contents: Macrocyclic and Linear Borazine-Arene CompoundsMacrocyclic oligomeric condensates formed by an alternate sequence of 2,4-difunctional borazines and aromatic 1,3-dihydroxy, 1,3-diamino, or l-amino-3-hydroxy compounds (1-4) are less stable than corresponding systems formed by O- or NH-linked borazines only. Besides of these compounds which have a pseudocage structure like the cyclic oligoborazines, several noncyclic oligomeric condensates have been prepared which exist of mono- or difunctional borazines and di- or monofunctional phenols, thiophenols, or aromatic amines (5- 13). The substances are characterized by analyses, mass and 1H-NMR spectroscopy.
    Notes: Oligomere, makrocyclische Kondensate, die alternierend aus 2,4-difunktionellen Borazinen und aromatischen 1,3-Dihydroxy-, 1,3-Diamino- oder 1-Amino-3-hydroxy-Verbindungen gebildet werden (1-4), sind weniger stabil als entsprechende Systeme, die nur aus O- oder NH-verbrückten Borazinen bestehen. Außer diesen Verbindungen, die ebenso wie die cyclischen Oligoborazine Pseudokäfigstruktur besitzen, wurden mehrere nicht cyclische oligomere Kondensate aus mono- oder difunktionellen Borazinen und di- bzw. monofunktionellen Phenolen, Thiophenolen bzw. aromatischen Aminen dargestellt (5-13). Die Verbindungen sind analytisch und durch ihre Massen- und 1H-NMR-Spektren charakterisiert.
