Rastogi, Gaurav K. published the artcileCu(I)/Fe(III) promoted dicarbonylation of aminopyrazole via oxidative C-H coupling with methyl ketones, COA of Formula: C6H6OS, the main research area is aminopyrazole methyl ketone copper iron dicarbonylation oxidative coupling catalyst; diketone aminopyrazole preparation.
Cu(I)/Fe(III) promoted C4-dicarbonylation of 5-aminopyrazole is developed. The strategy involved radical triggered direct oxidative coupling of 5-aminopyrazoles with Me ketones using aerial oxygen as a source of oxygen in newly generated carbonyl group. CuI is used as catalyst and FeCl3·6H2O is used as additive and the reaction proceeded at 120 °C in DMSO for 9-12 h. It is found that use of Cu(II) catalyst gives the thiomethylated product by reacting with DMSO instead of oxidative coupling. A plausible mechanism is also given.
