Intramolecular Site Exchange of Carbonyl Ligands in the Cluster Compounds Nonacarbonyl{μ3-[η3-(1,3,5-trithiane)]}triruthenium ([Ru3(CO)9{μ3-(η3-C3H6S3)}]) and (tert-Butyl Isocyanide)octacarbonyl-{μ3-[η3-(1,3,5-trithiane)]}triruthenium ([Ru3(t-BuNC)(CO)8{μ3-(η3-C3H6S3)}]) |

| Abstract: | Variable-temperature and -pressure 13C-NMR studies of the 1,3,5-trithiane-capped triruthenium clusters [Ru3(CO)9{μ3-(η3-1,3,5-trithiane)}] ( 1 ) and [Ru3(t-BuNC)(CO)8{μ3-(η3-1,3,5-trithiane)}] ( 2 ) revealed that CO site exchanges occur via an intramolecular merry-go-round process, involving a transition state mostly dissociative in character. |
