✦ Synopsis
General catalytic Cu(OAc) 2 /TEMPO in air or Cu(OAc) 2 /O 2 systems for the C N and C O cross-coupling reactions with arylboronic acid have been discovered. N-and O-vinylation have also been demonstrated.

The mildest method of N-vinylation has been discovered. The synthetic utilities of the N-and O-vinylated products include protecting group, cyclopropanation and Grubbs' ring closure metathesis reactions.
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 demonstrat
