Peripheral palladation of a Möbius aromatic [28]hexaphyrin Pd II complex was accomplished with strict regioselectivity. X‐ray structural analysis revealed the structure of the BINAPO‐ligated bispalladium complex (see figure). After the quantitative hydrochlorination, a Stille‐coupling reaction afforded β‐ethynylated derivatives in modest yields with maintenance of twisted Möbius aromatic system.
