A divergent reactivity of α-azidochalcones with metal β-diketonates for the synthesis of substituted pyrroles and indoles was described. Metal β-diketonates were applied as bifunctional reactive partners. With a copper complex, the synthesis of substituted pyrroles in micellar media via 2H-azirine intermediates was achieved under mild conditions, while with Fe(acac)2 as a catalyst, the reaction proceeded smoothly to yield indoles regioselectively. In the experiment, the researchers used many compounds, for example, copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4Electric Literature of C10H2CuF12O4).
copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4) belongs to copper catalysts. Copper has continued to be one of the most utilized and important transition metal catalysts in synthetic organic chemistry. Copper nanoparticles can also catalyze the coupling reaction of phenols, thiols, xanthogenates, nitrogen-containing nucleophiles, selenium ruthenium nucleophiles and the like.Electric Literature of C10H2CuF12O4
