The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 52409-22-0, Pd2(DBA)3, introducing its new discovery.
Molecular topology of pi-conjugated circuits becomes increasingly important in the chemistry of aromatic and antiaromatic compounds. meso-Pentafluorophenyl-substituted 5,35-(1,4-phenylene)bridged [56]dodecaphyrin was synthesized by condensation of 1,4-phenylene-bridged dicarbinol dimer and 5,10,15-tris-(pentafluorophenyl)tetrapyrrane followed by oxidation with DDQ and was oxidized to its [54]- and [52]congeners in a stepwise manner. Metalation of the [52]dodecaphyrin with Pd2(dba)3 gave two bis-PdII complexes that are isomers of metalation sites: anti and syn with regard to the 1,4-phenylene bridge. The anti-isomer was easily oxidized to its N-fused form, a quadruply twisted non-aromatic or weakly aromatic macrocycle. On the other hand, the syn-isomer was revealed to be the first example of Hueckel aromatic molecule with a quadruply twisted structure.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Related Products of 52409-22-0. In my other articles, you can also check out more blogs about 52409-22-0
