Kurzzusammenfassung:
Known procedures for the synthesis of K[CpRu(CO)2] (KRp) via reductive cleavage of the ruthenium dimer Rp2 were found to be inconsistent and have thus been revisited, and a revised protocol using K[HB(sec-Bu)3] (K-Selectride) as the reducing agent is now reported that gives yellow KRp in crystalline form in around 40\% yield. The structure of KRp·THF has been determined by X-ray diffraction, representing the first crystallographic characterization of an Rp– salt. Inevitably the reductive cleavage of Rp2 also gives a poorly soluble black solid as an additional product, which has now been analyzed by a variety of methods, including 13C MAS NMR spectroscopy using 13CO-labeled material. The black solid has been identified as a polymeric Cp/Ru/CO compound with both bridging and terminal CO ligands in a 3:1 ratio. The present report may stimulate the use of the [CpRu(CO)2]− (Rp–) anion, which has been barely exploited as yet in comparison to its popular congener [CpFe(CO)2]− (Fp–).
