Rh(III)-Catalyzed enone carbonyl directed annulative coupling of α-aroyl ketene dithioacetals and diazo compounds were realized via aryl and olefinic C-H bond activation. This transformation offered highly functionalized indanone derivatives bearing a quaternary carbon stereocenter at the β-position. The protocol exhibited high efficiency, broad substrate scope, and high compatibility with functional groups. In the experiment, the researchers used many compounds, for example, copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4Quality Control of copper(ii)hexafluor-2,4-pentanedionate).
copper(ii)hexafluor-2,4-pentanedionate (cas: 14781-45-4) belongs to copper catalysts. Transition metal-catalyzed chemical transformation of organic electrophiles and organometallic reagents belong to the most important cross-coupling reaction in organic synthesis. Copper of different valence states can be used to catalyze the coupling reaction, especially the Ullmann coupling reaction. Quality Control of copper(ii)hexafluor-2,4-pentanedionate
