WebNov 17, 2024 · Asymmetric hydroarylation. The hydroarylation reaction, the addition of a hydrogen atom and an aryl group to an alkene, offers a straightforward approach to chiral alkylarenes via C–C bond formation. A wide array of nickel-catalyzed hydroarylation reactions have been reported. 10 To date, three strategies have been developed for … WebOct 11, 2010 · These results suggest that, although the diffusion of bulky alkene and oxidant reagents can be a rate-limiting factor in MOF-catalyzed asymmetric reactions, the catalytic activity of the CMOFs with large open channels (such as CMOFs 2 and 4 in the present study) is limited by the intrinsic reactivity of the catalytic molecular building blocks. motoscout24 italia
