Cu(II)-Catalyzed C-N, C-O, C-Cl, C-S, and C-Se Bond Formation via C(sp2)-H Activation Using 7-Azaindole as Intrinsic Directing Group was written by Kumar, Mohit. And the article was included in Journal of Organic Chemistry in 2021.HPLC of Formula: 271-63-6 This article mentions the following:
A general protocol has been developed for the construction of carbon-heteroatom (C-N, C-Cl, C-O, C-S & C-Se) bonds using the bench stable, earth-abundant, and environmentally benign copper catalyst. Only oxygen is sufficient to regenerate the copper catalyst. Control experiments suggested that the proto-demetalation step is reversible. Depending on the coupling partner the reaction follows either disproportionation or radical pathways to complete the catalytic cycle. The synthetic utility of the developed protocol has been demonstrated via various functional groups transformations. In the experiment, the researchers used many compounds, for example, 1H-Pyrrolo[2,3-b]pyridine (cas: 271-63-6HPLC of Formula: 271-63-6).
1H-Pyrrolo[2,3-b]pyridine (cas: 271-63-6) belongs to indole derivatives. Indole is an important structural motif of various drugs, therapeutic leads besides its prevalence in numerous natural products, agrochemicals, perfumery, and dyes. It is used in perfumery and in making tryptophan, an essential amino acid, and indoleacetic acid (heteroauxin), a hormone that promotes the development of roots in plant cuttings.HPLC of Formula: 271-63-6
