Palladium-Catalyzed Catellani-Type Bis-silylation and Bis-germanylation of Aryl Iodides and Norbornenes

Abstract

A palladium-catalyzed three-component reaction of aryl iodides, norbornenes, and hexamethyldisilane/hexamethyldigermane has been developed for the assembly of highly functionalized disilanes/digermanes. The potential synthetic utility of this methodology was highlighted by the late-stage manipulations of natural products and the iterative C-H bis-silylation for the synthesis of highly decorated arenes.
