properties

Triruthenium dodecacarbonyl is an orange-colored solid that is fairly air and lightfast. It is soluble in almost all organic solvents , especially acetone , but insoluble in water.

use

Triruthenium dodecacarbonyl is used as a starting material for carbonyl clusters and as a hydrogen transfer catalyst. It is used for the reductive carbonylation of aromatic nitro compounds to form carbamates and for the allylic amination of activated olefins by nitroarenes.
