Ruthenium-Catalyzed Hydroarylations of Methylenecyclopropanes: Mild C−H Bond Functionalizations with Conservation of Cyclopropane Rings

Abstract

Ring conservation was observed in the first catalytic intermolecular hydroarylation of methylenecyclopropanes via C-H bond functionalization, a remarkable reactivity mode for a transformation proceeding through (cyclopropylcarbinyl)metal intermediates.
