Cp^*Ru(acac)—A Coordinatively Unsaturated, Stable 16‐Valence‐Electron Complex

Abstract

An unusually clear demonstration of the ease of addition of two-electron donor ligands to the title complex 1 is provided by the molecular structure shown on the right. Complex 1 is readily accessible from [{Cp*RuOMe}2] and acetylacetone. The air-sensitive, intensely red complex 1 adds CO and phosphane very rapidly and can be cleaved with cations such as Zn2⊕ and Mg2⊕ to give the very versatile Cp*Ru⊕ fragment.
