alkylation of (hetero)arenes using cyclopropanols as a reactive and efficient coupling partner under oxidative conditions has been developed. This coupling occurred at room temperature via C–H activation of arenes and C–C cleavage of cyclopropanols. Various types of (hetero)arenes (indolines, carbazole, tetrahydrocarbazole, pyrrole, thiophene, etc.) were all successfully reacted under the present conditions

Rhodium-catalyzed C–Hactivation of arenes has been established as an important strategy for the rapid construction of new bonds. On the other hand, ring-opening of readily available cyclopropanols has served as a driving force for the coupling with various nucleophiles and electrophiles. Nevertheless, these two important areas evolved separately, and coupling of arenes with cyclopropanols viaC–Hactivation has

An efficient Rh(III)-catalyzed C–Hoxidative alkylation of N-aryl-7-azaindoles with cyclopropanols by merging tandemC–H and C–Ccleavage was developed. This transformation features mild reaction conditions, high regioselectivity, and excellent functional group compatibility. The resulting β-aryl ketone derivatives can be readily transformed into 7-azaindole-containing π-extended polycyclic heteroarenes

azomethine imine with cyclopropanol through in situ ring-opening, followed by cascade intramolecular C- and N-nucleophilic addition. In this tandem process, cyclopropanol acts as not only an alkylating agent but also masked nucleophile and electrophile to participate in the construction of both the indane and the bicyclic pyrazolidinone scaffolds. To our knowledge, such a cascade reaction pattern has not been
