¹H and ¹³C NMR spectra of multibridged [2n]cyclophanes

The 1 H and 13 C NMR spectra of all [2 n ] cyclophanes with the same substitution pattern in both benzene rings and of the skew [2.2.2](1,2,4)(1,2,5)cyclophane were assigned by one‐dimensional NOE difference and two‐dimensional correlation spectroscopy. The 1 H NMR spectra of the bridge protons including the 13 C satellites of the symmetrical compounds [2.2]paracyclophane, [2.2.2](1,3,5)cyclophane and superphane were analysed by iterative methods. Chemical shifts and H,H coupling constants are discussed with regard to molecular geometries.
