Abstract

Acyclic and cyclic esters, as well as anhydride (boroxine) of phenylboronic acids are efficient phenylating agents in copper promoted C N and C O bond cross-coupling reactions. The first successful C N cross-coupling of a heterocyclic boronate with heteroarenes, such as indazole, has been demonstrated.
