  Using Rh(III)-Catalyzed C–H Activation as a Tool for the Selective Functionalization of Ketone-Containing Molecules

  摘要：

  Due to the strong potential of C H activation in many areas of organic chemistry, the use of a pre-existing carbonyl group for the installation of a directing group to enable selective and predictable alpha-alkenylation with activated olefins as coupling partners is described. This Heck-type reaction would then lead either to beta,gamma-unsaturated ketones or to variously substituted 1,4-butadienes depending on the conditions used for the cleavage of the directing group.
