Synthesis and Reactivity of Ruthenium-Antimony Carbonyl Clusters
The reaction of Na[HRu3(CO)11] (2) with SbPh2Cl in dry tetrahydrofuran (THF) afforded the cluster Ru3(CO)10(μ-H)(μ-SbPh2) (3); in dry dichloromethane (DCM), the six-membered ring Ru6(CO)20(μ-H)2(μ-SbPh2)2 (4) was obtained instead. The trimethylamine N-oxide (TMNO) activated reaction of Ru3(CO)12 (1)...
