A Cu-catalyzed stereoselective phosphono-hydrazonation of terminal alkynes with alkyl carbazates and diarylphosphine oxides is described. This methodol. provides facile access to a variety of β-hydrazonophosphine oxides in satisfactory yields. The reaction proceeds under mild conditions and exhibits good functional group tolerance. A mechanism featuring persulfate-mediated oxidative generation of phosphinoyl radicals and Cu-assisted hydrazonation is proposed. In the experiment, the researchers used many compounds, for example, Copper(II) trifluoromethanesulfonate (cas: 34946-82-2Quality Control of Copper(II) trifluoromethanesulfonate).
Copper(II) trifluoromethanesulfonate (cas: 34946-82-2) belongs to copper catalysts. Copper has continued to be one of the most utilized and important transition metal catalysts in synthetic organic chemistry. Due to these characteristics, copper nanoparticles have generated a great deal of interest especially in the field of catalysis. Quality Control of Copper(II) trifluoromethanesulfonate
