Chmielewski, Piotr J.; Latos-Grazynski, Lechoslaw published the artcile< EPR and 2H NMR studies on the oxidation of nickel(II) tetraphenylcarbaporphyrin to form novel organometallic Ni(III) complexes>, Synthetic Route of 112-63-0, the main research area is EPR oxidation nickel 2 tetraphenylcarbaporphyrin complex; NMR oxidation nickel 2 tetraphenylcarbaporphyrin complex; electrochem oxidation nickel 2 tetraphenylcarbaporphyrin complex.
One-electron oxidation of nickel(II) 5,10,15,20-tetraaryl-2-aza-21-carbaporphyrin ((CTPP)NiII) and nickel(II) 2-methyl-5,10,15,20-tetraaryl-2-aza-21-carbaporphyrin ((MeCTPP)NiII) gave rare organonickel(III) derivatives The half-wave potential for the 1st oxidation of (CTPP)NiII and (MeCTPP)NiII is 0.66 V and 0.72 V, resp. (vs. SCE, CH2Cl2 solution, TBAP). The EPR spectral patterns of the 1-electron-oxidized species were determined at 293 and 77 K. In both temperatures the spectral parameters markedly depend on the axial ligand introduced by oxidants or in metathesis. In each case the spin-Hamiltonian parameters (gav > 2.1 (77 K) or giso > 2.1 (293 K)) reveal a metal-centered oxidation rather than a cation radical formation (giso ≈ 2.002). The localization of the 1-electron oxidation on the nickel ion was supported by the observation of 61Ni hyperfine splitting. The 2H NMR studies, carried out for pyrrole deuterated derivatives: (CTPP-d7)NiIIIBr, (CTPP-d7)NiIII(NO3), and (MeCTPP-d3)NiIIIOH, confirmed independently by the nickel(III) electronic structure.
Inorganic Chemistry published new progress about Electrochemical oxidation. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Synthetic Route of 112-63-0.
