Efficient Synthesis of Tris(acetonitrile)‐(η⁵‐cyclopentadienyl)‐ ruthenium(II) Hexafluorophosphate <i>via</i> Ruthenocene

Abstract

Abstract [Ru(η 5 ‐C 5 H 5 )(CH 3 CN) 3 ][PF 6 ] ( 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)][PF 6 ] ( 4 ) avoids both highly toxic thallium reagents and the need for a photoreactor.
