Reductive metalation of decaphyrin with [Pd2-(dba)3] provided a Hückel aromatic decaphyrin PdII complex, which was readily oxidized upon treatment with DDQ to produce a Hückel antiaromatic decaphyrin PdII complex. In CH2Cl2 solution the latter complex underwent slow tautomerization to a Möbius aromatic decaphyrin PdII complex which exists as a mixture of conformers in dynamic equilibrium. To the best of our knowledge, these three PdII complexes represent the largest Hückel aromatic, Hückel antiaromatic, and Möbius aromatic complexes to date.
