Abstract

The Heck arylation belongs to the most important methods for CÀC bond formation and has therefore found widespread application in organic synthesis.[1] Various halides or pseudo halides are readily cross-coupled with olefins under Pd catalysis. In contrast, the oxidative Heck reaction using aryl boronic acids in combination with an external oxidant and a Pd catalyst has been less intensively investigated.[2, 3] Oxidative Heck-type coupling is ...
