Synthesis, structure and electrochemical properties of 1-ferrocenyl-3-cymantrenyl-containing β-diketone, pyrazole and mixed-metal chelated complex of p-cymene-ruthenium-iodide

Synthesis, Characterization, and Electrochemistry of Diferrocenyl β-Diketones, -Diketonates, and Pyrazoles

“…In this respect, it was found that ferrocenyl-functionalization of pyrazoles enhances their biological activities [ 55 , 56 , 57 , 58 , 59 ]. Facile synthesis methods of ferrocenyl-substituted pyrazoles were reported [ 60 , 61 , 62 , 63 , 64 , 65 , 66 ], with only a brief comment about the parent diferrocenyl NH-pyrazole in 1963 [ 66 ].…”

Synthesis, structures, electrochemical and quantum chemical investigations of Ni(ii) and Cu(ii) complexes with a tetradentate Schiff base derived from 1-(2-thienyl)-1,3-butanedione

“…[2][3][4] The versatility of Schiff base ligands arises from their structural and electronic variations, achieved by varying the stereo-electronic nature of the substituents incorporated on their skeletons via the β-diketone starting materials. 5 Those easily synthetized and easily tunable dicarbonyl building blocks, presenting a keto-enol tautomerism, [6][7][8] are readily tailored to bring about donor, acceptor, polymerizable, or electroactive groups at the three carbon atoms constituting the propane-1,3-dione skeleton. [7][8][9][10][11][12][13][14] β-diketones containing a thiophene group are of particular interest because they can be used as starting materials for the construction of Schiff base derivatives and metal complexes tagged with electroactive thiophene moieties, thus allowing electrochemical polymerization to conveniently enable the direct preparation of an insoluble polymeric coating on the surface of the electrode.…”

[15][16][17] In this context, we have recently disclosed the generation and characterization of a polythienyl-containing β-diketonate copper(II) compound and its deposition on an electrode, upon electropolymerization of the [Cu(II)-bis-{1-(2-thienyl)-3-(3-thienyl)propane-1,3-dionato}] complex using potentiodynamic method.…”
