Abstract

No CO: Fluoroborylene (BF), isoelectronic with CO and N2, can be trapped by a transition metal. The structurally characterized complex [{CpRu(CO)2}2(μ-BF)] contains an unsupported bridging BF ligand, which is unprecedented in the structural chemistry of CO. With AlCl3 , metal-bound CO coordinates through the O atom without bond rupture, while the more polar and less π-bonded BF ligand is heterolytically cleaved (see picture).
