The potassium salt of (η 6-3a,7a-azaborindenyl)Cr(CO) 3 was prepared in a THF solution at -60°C. Warming to -40°C causes the Cr(CO) 3 group to undergo haptotropic migration to the five-membered ring. DFT calculations suggest that the preferred intramolecular pathway involves Cr(CO) 3 coordination to the boron rather than the nitrogen side of the ligand.
