Series of new oxaporphyrins were isolated from the reaction of furan-1,4-diol, pyrrole, and an aldehyde under Lindsey’s conditions, which gives easy access to ester group functionalized oxaporphyrins. The ester substituents can be readily hydrolyzed to terminal carboxylic acid in the presence of KOH. The Zn(II) oxaporphyrins have been synthesized from the reaction of free base with ZnCl 2 ...
Reactions of IrCl3·xH2O with the ligands, 2-[(phenylamino)phenylazo]pyridine (HL1a) and 2-[(p-tolylamino)phenylazo]pyridine (HL1b) produce [Ir(L1)2]Cl (L1 = L1a, [1]Cl and L1 = L1b, [2]Cl) along with many unidentified products. The iridium complexes have been characterized by various techniques such as X-ray crystallography, mass spectrometry, 1H and 13C NMR, cyclic voltammetry and absorption studies...
