摘要
Static and dynamic stereochemistry of the title compounds was studied by X-ray crystallography and variable-temperature NMR. Stereomutation in solution was quantitatively analyzed in terms of two rate processes in which the nitrogen substituents pass over one of the benzene rings of the triptycene skeleton.
