Abstract

The first example of a complex containing an η3-coordinated borirene ligand bound to a single metal atom is prepared by photolytic transfer of an arylborylene ligand to diphenylacetylene and loss of three CO ligands from the precursor. The η3-borirene complex possesses a chromium(0) atom bound additionally to one phenyl group in an η6 fashion. The complex is formed in 15% isolated yield accompanied by the corresponding metal-free borirene, which is isolated in a 62% yield. The bonding between the chromium center and the borirene ring is studied computationally by DFT methods.
