Synthesis and characterization of N3Py2 ligand-based cobalt(II), nickel(II) and copper(II) catalysts for efficient conversion of hydrocarbons to alcohols

Electrocatalytic water oxidation by copper(ii) complexes with a pentadentate amine-pyridine ligand

“…Ligand pydien was synthesized according to a method given in the literature. 32 Ligand mpydien was synthesized following the procedures of pydien synthesis except that 2,2′-diamino- N -methyldiethylamine was used instead of diethylenetriamine.…”

Cobalt(II) Bipyrazolate Metal–Organic Frameworks as Heterogeneous Catalysts in Cumene Aerobic Oxidation: A Tag-Dependent Selectivity

“…Several literature examples featuring both homogeneous and heterogeneous cobalt-based systems can be found. As a representative example, the [Co­(N 3 Py 2 )­(H 2 O)]­(ClO 4 ) 2 and [Co­(N 3 Py 2 )­(CH 3 CN)]­(BPh 4 ) 2 complexes (N 3 Py 2 = κ 5 N -pentadentate pyridine-based ligand) reported in 2017 belong to the former class. The latter family is definitely larger, spanning from Co-salen polymers, a Co­(OAc) 2 /SiO 2 xerogel composite, and simple CoX 2 salts (X – = Cl – , OAc – , acac – ) to the mixed-valence spinel Co 3 O 4 and modified cobalt oxides …”

Modulating the electrocatalytic activity of mononuclear nickel complexes toward water oxidation by tertiary amine group

“…S3†). 18 As for complex 5 , there is no characteristic absorption peak in the visible region, similar as the absorption spectrum of complex 4 . 14 The UV-visible absorption spectra of complexes 1–3 keep unchanged when dissolved in PBS at pH 9.0 (Fig.…”
