Intramolecular Alkene-Alkene Coupling via Rh(III)-Catalyzed Alkenyl sp2 C-H Functionalization: Divergent Pathways to Indene or α-Naphthol Derivatives was written by Maraswami, Manikantha;Diggins, Thomas;Goh, Jeffrey;Tio, Raymond;Ong, Wan Qing Renee;Hirao, Hajime;Loh, Teck-Peng. And the article was included in ACS Catalysis in 2021.Electric Literature of C10H11BrO2 This article mentions the following:
Highly selective synthesis of either indene or 1-naphthol derivatives through intramol. alkene-alkene cross-coupling is reported. The reaction works with different alkene pairs that couple to give the corresponding products in good to satisfactory yields. The indene products of authors reaction also allow further derivatization. The reaction pathway is dependent on alkene functionalities. In the experiment, the researchers used many compounds, for example, Ethyl (2-bromophenyl)acetate (cas: 2178-24-7Electric Literature of C10H11BrO2).
Ethyl (2-bromophenyl)acetate (cas: 2178-24-7) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact. Many of the alkyl bromine derivatives are excellent alkylating agents since bromides are good leaving groups. Tribromides, like tetrabutylammonium tribromide, are used as a solid source of bromine. N-bromosuccimide (NBS) is used for the selective bromination of allylic bonds.Electric Literature of C10H11BrO2
