  Balance between Allylic C−H Activation and Cyclopropanation in the Reactions of Donor/Acceptor-Substituted Rhodium Carbenoids with trans-Alkenes

  摘要：

  Rhodium(II)-catalyzed reactions of aryldiazoacetates with (E)-aryl-substituted alkenes generate C-H insertion products and/or cyclopropanes. The product distribution is influenced by the nature of the donor group on the carbenold, the structure of the (E)-aryl-substituted alkenes, and the rhodium catalyst.
