RESUMO
The reactions of boratabenzene and borataphenanthrene anions with group 11 Ph3PMCl reagents furnished η2 coordination complexes, with the exception of the copper boratabenzene species that adopted an η6 mode. The binding of arene ligands to copper in an η6 manner is rare, and altering the ancillary ligand on copper to an N-heterocyclic carbene switched the binding of the boratabenzene to η2, indicating that such ligands are capable of vacating coordination sites. The η2 coordination complexes bind side-on, akin to olefins, via a borataalkene unit, although with the carbon atom much more proximal to the metal center than boron.
