摘要

This article describes the development of new auxiliary-accelerated Heck multiarylations by intramolecular presentation of the oxidative addition complex. The introduction of a specific, palladium-coordinating dimethylamino group allows for the desired chelation-accelerated and chelation-controlled tri-and diarylation reactions. We report (a) the first example of a Heck triarylation process,(b) highly selective palladium-catalyzed diarylations of alkyl vinyl ...
