The first direct general method for N-Me aziridination of electron-deficient olefins, enones, was described using N-methyl-O-tosylhydroxylamine as the aminating agent in the presence of Cu(OTf)2 catalyst. The aziridination of vinyl ketones, hitherto unknown for N-Me as well as N-H, was achieved efficiently. The open-flask reaction was stereospecific, operationally simple and additive-free. It also affords N-H aziridinated products under a similar reaction condition efficiently. In the experiment, the researchers used many compounds, for example, Copper(II) trifluoromethanesulfonate (cas: 34946-82-2Electric Literature of C2CuF6O6S2).
Copper(II) trifluoromethanesulfonate (cas: 34946-82-2) belongs to copper catalysts. The applications of Copper-based nanoparticles have received great attention due to the earth-abundant, low toxicity and inexpensive. The copper-mediated C-C, C-O, C-N, and C-S bond formation is a part of one oldest reaction, emphasizing the Ullmann cross-coupling reaction.Electric Literature of C2CuF6O6S2
