  Rh(III)-Catalyzed C–H Activation with Allenes To Synthesize Conjugated Olefins

  摘要：

  Rh-III-catalyzed C-H activation with allenes produces highly unsaturated conjugated olefins. The reaction is applicable to both olefin and arene C(sp(2))-H and is compatible with a variety of functional groups. The products can be further transformed into other important skeletons through Diels-Alder reaction and intramolecular transesterification.
