Pd-Catalyzed π-Chelation Assisted ortho-C–H Activation and Annulation of Allylarenes with Internal Alkynes
摘要:
The synthesis of highly substituted naphthalenes from allylarenes and alkynes is described. This reaction proceeds via pi-coordination of an allylic carbon-carbon double bond to the Pd(II) center and is followed by ortho selective C-H bond activation.
