In the present study, the unusually stable diacetyliminoxyl radical I was presented as a ”golden mean” between transient and stable unreactive radicals. It was successfully employed as a reagent for oxidative C-O coupling with β-dicarbonyl compounds II (R = Me, Bu, chloro, benzyl) and R1C(O)CH(R2)C(O)R3 (R1 = Me, phenyl; R2 = Me, allyl, Ph, benzyl, chloro; R3 = Me, Ph, ethoxy). Using this model radical the catalytic activity of acids, bases and transition metal ions in free-radical coupling was revealed. In the experiment, the researchers used many compounds, for example, copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4Computed Properties of C10H2CuF12O4).
copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4) belongs to copper catalysts. The applications of Copper-based nanoparticles have received great attention due to the earth-abundant, inexpensive and low toxicity. Copper nanoparticles can also catalyze the coupling reaction of nitrogen-containing nucleophiles, phenols, thiols, xanthogenates, selenium ruthenium nucleophiles and the like.Computed Properties of C10H2CuF12O4
