Synthesis of new palladium(II) compounds with several bidentate nitrogen-donor ligands: Structural analyses by 1H and 13C{1H} NMR spectroscopy and crystal structures

Synthesis, Characterization, DFT, and Thermogravimetric Analysis of Neutral Co(II)/Pyrazole Complex, Catalytic Activity toward Catecholase and Phenoxazinone Oxidation

“…The V max value was found to be 0.631 µmol•L −1 •min −1 and K m = 0.007 mol•L −1 . These kinetic parameters values are compatible with the results of others using similar complexes [3][4][5][6][7][8][9][10][11]. In addition, by comparing this with results from the literature, one can classify the desired Co(II)/pyrazole complex as working well in the catecholase process in the absence of an oxidizing agent besides atmospheric oxygen.…”

“…N-pyrazole derivative ligands and their complexes are used because of their stability, catalytic coordination abilities and versatility [1,2]. In particular, Co(II)/pyrazole complexes have received attention in several applications, where most researchers are using these complexes as catalysts, with an eye on their promising medical role [3][4][5][6][7].…”

A new dinuclear copper(II) complex of unexpected formation with the 1-[2-(ethylamino)methyl]pyrazole ligand presents a curious Ferris wheel-like shape at supramolecular self-assembly

“…The syntheses of these ligands and the studies of their reactivity with Ni(II), Co(II), Zn(II) and Cu(II) were carried out by Driessen et al and Sheu et al [5][6][7][8][9][10]. Other studies of the reactivity of theses ligands are reported by Calderazzo et al using Fe(II) [11] and Carpentier et al using Al(III) and Zn(II) [12] as coordination metals.More recently, the syntheses of new types of N-alkylaminopyrazole ligands and the evaluation of their reactivitywith Rh(I) [13][14][15][16], Pd(II) [17][18][19][20], Pt(II) [21], Zn(II) [22] and Cd(II) [23] have been continued by our group. Some of them have been used in the synthesis and stabilization of nanoparticles, even as metal recognizer molecules in metal sensing systems [24][25][26].…”
