NEW 3-(2-PYRIDYL)-1,2,4-TRIAZOLE DERIVATIVES AND THEIR PALLADIUM (II) COMPLEXES

The article is devoted to investigation of coordination compounds of palladium (II) with 3-(2-pyridyl)-1,2,4-triazole derivatives containing amino groups. We syntesized 4 ligands and 4 new coordination compounds. An interesting after removing of BOC-protection, NH2-group is still uncoordinated. In 1H NMR spectra of complexes was a significant shift of the ortho-pyridine proton in a low-field area, which prove proposed structure. This may be due to its closeness to the lone electron pair of the nitrogen cycle of the second triazole ligand
