Heinemann, Jan und Böttcher, Hans-Christian (2022): Triphenylmethyl Thionitrite: An Efficient NO Transfer Reagent During the Synthesis of a Triruthenium Nitrosyl Cluster. In: Zeitschrift für Anorganische und Allgemeine Chemie, Bd. 648, Nr. 6 [PDF, 726kB]

Abstract

The synthesis and structural characterization of the novel triruthenium nitrosyl cluster [Ru-3(mu-NO)(CO)(5)(mu-H)(mu-PBu2t)(2)(mu-dppm)] (2) is described. Compound 2 was obtained by the reaction of the 46-valence electron cluster [Ru-3(mu-CO)(CO)(4)(mu(3)-H)(mu-H)(mu-PBu2t)(2)(mu-dppm)] (1) with nitric oxide and on the other hand in a more efficient way by the reaction of 1 with the nitrosyl transfer reagent triphenylmethyl thionitrite (TTN). The reaction of 1 with NO was outlined in dichloromethane whereas the reaction with TTN was realized in THF. Both methods worked at ambient temperature affording compound 2 in high yield. Temporarily we found that the transformation of 1 with NO was accompanied by a fast side-reaction resulting in a further substitution of CO ligands. The molecular structure of 2 in the crystal was confirmed by single-crystal X-ray diffraction.
