《”Bulky-Yet-Flexible” α-Diimine Palladium-Catalyzed Reductive Heck Cross-Coupling: Highly Anti-Markovnikov-Selective Hydroarylation of Alkene in Air》 was published in Journal of Organic Chemistry in 2020. These research results belong to Yang, Xu-Wen; Li, Dong-Hui; Song, A-Xiang; Liu, Feng-Shou. Synthetic Route of C9H11Br The article mentions the following:
To pursue a highly regioselective and efficient reductive Heck reaction, a series of moisture- and air-stable α-diimine palladium precatalysts was rationally designed, readily synthesized, and fully characterized. The relationship between the structures of the palladium complexes and the catalytic properties was investigated. It was revealed that the “”bulky-yet-flexible”” palladium complexes allowed highly anti-Markovnikov-selective hydroarylation of alkenes with (hetero)aryl bromides under aerobic conditions. Further, synthetic application of the present protocol could provide rapid and straightforward access to functional and biol. active mols. In the experiment, the researchers used many compounds, for example, 1-Bromo-2-isopropylbenzene(cas: 7073-94-1Synthetic Route of C9H11Br)
1-Bromo-2-isopropylbenzene(cas: 7073-94-1) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals.Synthetic Route of C9H11Br Organobromine compounds have fallen under increased scrutiny for their environmental impact.
