Binuclear Complexes of Bis-Chelating Ligands Based on [1,4]Dioxocino[6,5-b:7,8-b′]dipyridine Moieties
摘要:
Binucleating ligands based on a [1,4]dioxocino[6,5-b: 7,8 -b']dipyridine (doxpy) core were prepared and characterized. They all present two equal chelating moieties each one including one N, O, or S donor in addition to a pyridinic nitrogen. At least one d(8) ion (Pd-II or Pt-II) complex was prepared for each type of ligand. The stereochemical behavior of the ligands and the complexes, along with the cooperative catalytic ability of two Pd-II centers are discussed.
