Abstract

(Chemical Equation Presented) Round the twist: Metalation of [36]octaphyrin 1 provided the Möbius aromatic Pd2 complex 3 as well as the Hückel antiaromatic Pd2 complex 2. This method can be applied to other expanded porphyrins and Group 10 metal ions. The aromatic/antiaromatic character was supported by NMR spectrscopy, NICS calculation, and two-photon absorption measurements.
