Triphenylmethyl Thionitrite: An Efficient NO Transfer Reagent During the Synthesis of a Triruthenium Nitrosyl Cluster

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