Rutheniumcluster als Katalysatoren fuer die Carbonylierung von cyclischen Aminen

Article abstract of DOI:10.1016/0022-328X(89)80122-6

The tri- and tetra-nuclear ruthenium clusters Ru3(CO)12, ^- and ^- have been found to catalyse the carbonylation of cyclic amines such as piperidine, 3-methylpiperidine, pyrrolidine, heptamethylene imine, morpholine and piperazine to give the corresponding formamides.The catalytic reaction works with only carbon monoxide or a mixture of carbon dioxide and hydrogen.In the case of the neutral catalyst precursor, carbamoyl clusters of the type (μ₂-H)Ru3(CO)10(μ₂,η²-OCNR2) have been isolated from the reaction mixture.
