-034Transition-Metal-Catalyzed Carbenoid Reactions of Sulfonium Ylides.-The Rh(II)-and Cu(I)-catalyzed decomposition of diphenylsulfonium methylide (II) in the presence of various olefins is studied in order to develop a synthetic alternative for carbenoid olefin cyclopropanation that replaces toxic and explosive diazo compounds. For comparison the same reactions are studied using diazoacetate (V). The product distribution for the Rh(II…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
