    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.

    Description / Table of Contents: 9.9′-Diphenyl-[9.9′]bifluorenyl: a True Hexaarylethane.9.9′-Diphenyl-[9.9′-13C2][9.9′]bifluorenyl (3) was prepared via biphenyl-2-[13C]carboxylic acid, [9-13C]fluorenone, 9-hydroxy-9-phenyl-[9-13C]fluorene and 9-chloro-9-phenyl-[9-13C]-fluorene. The 13C n.m.r. spectrum of the 9-phenyl-[9-13C]fluorenyl dimer proves the hexaarylethane structure 3.
    Notes: 9.9′-Diphenyl-[9.9′-13C2][9.9′]bifluorenyl (3) wurde über [Carboxyl-13C]Biphenyl-carbon-säure-(2), [9-13C]Fluorenon, 9-Hydroxy-9-phenyl-[9-13C]fluoren und 9-Chlor-9-phenyl-[9-13C]fluoren dargestellt. Das 13C-NMR-Spektrum des 9-Phenyl-[9-13C]fluorenyl-Dimeren beweist die Hexaaryläthan-Struktur 3.
