Palladium Vacataporphyrin Reveals Conformational Rearrangements Involving Hueckel and Mobius Macrocyclic Topologies

摘要

5,10,15,20-Tetraaryl-21-vacataporphyrin (butadieneporphyrin, an annulene-porphyrin hybrid) which contains a vacant space instead of heteroatomic bridge acts as a ligand toward palladium(II). The metal ion of square-planar coordination geometry is firmly h
