Graphical Abstract

Rare organometallic complexes can be stabilized by using an N-confused system as a carbon ligand. A stable organocopper(II) compound of N-confused calix[4]phyrin has been characterized by X-ray crystallography (see picture). Complete π conjugation was found not to be a prerequisite for the formation of the metal–carbon bond.
