Abstract:The influence of anionic and cationic co‐surfactants in nonionic microemulsions on the performance of chiral Rh‐norbornadiene complexes with different counterions in the 1,2‐addition of phenylboronic acids to N‐tosylimines is described. Catalytic studies revealed the unique role of the counterion and the type of co‐surfactant. NMR experiments and the calculated intrinsic binding orbitals suggest that the anion exchange with co‐surfactant accelerates the formation of the catalytically active Rh‐OH complex, thus… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
