Abstract
[Ru(η5‐C5H5)(CH3CN)3][PF6] (1), a versatile precursor to catalysts containing the CpRu+ complex fragment, can be obtained in high yield via Cp/naphthalene exchange in ruthenocene. This new route via the complex [RuCp(naphthalene)][PF6] (4) avoids both highly toxic thallium reagents and the need for a photoreactor.
