摘要：

Variable-temperature and -pressure C-13-NMR studies of the 1,3,5-trithiane-capped triruthenium clusters [Ru3(CO)9{mu3-(eta3-1,3,5-trithiane)}] (1) and [Ru3(t-BuNC)(CO)8{mu3-(eta3-1,3,5-trithiane)}] (2) revealed that CO site exchanges occur via an intramolecular merry-go-round process, involving a transition state mostly dissociative in character.
