In this work, we are interested in finding new catalysts for catecholase, whose principle is
based on the oxidation reaction of catechol to o-quinone. In this context, we have studied a …

Herein, new substituted ligands based on pyrazole (L1–L4) were synthesized via a one-step
by condensing (1 H-pyrazole-1-yl) methanol with different primary amine compounds. The …

The in situ copper (II) complexes of six pyrazole and pyridine based ligands: 1-[5-methyl-1-
pyridin-2-yl-1H-pyrazol-3-yl] methanol L1, 2-(3, 5-dimethyl-pyrazol-1-yl)-pyridine L2,(5 …

Two novel thiosemicarbazones ligands have been synthesized and characterized by FT-IR,
ESI-MS, 1 H NMR, and also by single-crystal X-ray diffraction for L1. The crystal structure …

Four tridentate ligands L1-L4, namely N, N-bis ((3, 5-dimethyl-1H-pyrazol-1-yl) methyl)
pyridin-2-amine: L1, 5-chloro-N, N-bis ((3, 5-dimethyl-1H-pyrazol-1-yl) methyl) pyridin-2 …

The high catalytic activity of catechol oxidation in atmospheric oxygen signified the
selectivity and efficiency of the metalloenzyme [CuSO 4 L], with L is 5 chloro-N-((3, 5 …

New excellent catalysts for the oxidation of catechol to o-quinone were developed in this
study by the combination of some benzodiazepine derivatives ligands with copper (II) salts …

In the present work, catecholase activity is presented. The complexes were prepared by
condensation of the organic ligand pyrazolyl L 1–L 4 and copper (II) ion in situ. The pyrazolyl …

The purpose of this study is to demonstrate the synthesis of pyrazole-based ligands and to
evaluate their catalytic properties in the oxidation reaction of catechol to o-quinone. The …

In this work, we were interested in the search for new catalysts for catecholase, whose
principle is based on the oxidation reaction of catechol to o-quinone. In this context, a series …
