The authors demonstrate the synthesis and characterization of regioisomeric late transition metal-aluminum heterobimetallic complexes containing 3- and 4-oxypyridine ligands which bridge between the aluminum and transition metal center (Rh or Ir). Combined exptl. and theor. data allow for direct comparison of the electronic effect of the two different aluminum-containing ligands on the late transition metal center. In combination with electronic data regarding previously reported 2-oxypyridine bridged systems, the authors report a measurable decrease in ligand donor power as the regiosubstitution of the oxypyridine bridge is varied from 2- to 4- to 3-. In all cases, addition of aluminum is found have a minimal effect on the donor ability of the oxypyridine bridge in dichloromethane solution In the experiment, the researchers used many compounds, for example, Pyridin-4-ol (cas: 626-64-2Recommanded Product: 626-64-2).
Pyridin-4-ol (cas: 626-64-2) belongs to pyridine derivatives. In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. Many analogues of pyridine are known where N is replaced by other heteroatoms . Substitution of one C–H in pyridine with a second N gives rise to the diazine heterocycles (C4H4N2), with the names pyridazine, pyrimidine, and pyrazine.Recommanded Product: 626-64-2
