    Description / Table of Contents: Structure of Triarylmethyl DimersStructure 3 is confirmed for the dimer of triphenylmethyl (1) by 13C. n.m.r. spectra of [α-13C]triphenylmethyl dimer, the synthesis of which is described. The interpretation given for the proton resonance of 1-dimer2 is also supported by the 1H. n.m.r. spectrum of tris-(4-deuterophenyl)methyl dimer. However, for 9-phenylfluorenyl dimer the hexaarylethane structure 4 is proposed on the basis of the 1H. n.m.r. spectrum.
    Notes: 13C-NMR-Spektren des [α-13C]Triphenylmethyl-Dimeren, dessen Synthese beschrieben wird, beweisen die Struktur 3 für das dimere Triphenylmethyl (1). Das 1H-NMR-Spektrum des Tris-[4-deutero-phenyl]-methyl-Dimeren bestätigt ebenfalls die Interpretation der Protonenresonanz des 1-Dimeren2 im Sinne der Formel 3. Für das 9-Phenyl-fluorenyl-Dimere wird dagegen auf Grund des 1H-NMR-Spektrums die Struktur eines echten Hexaaryläthans 4 vorgeschlagen.
