Abstract
The present invention provides methods for the preparation of compounds of the formula (Formula I): L.sub.y M(CO).sub.z wherein M is Ru or Os, each L is independently a neutral ligand, y=1-4, and z=1-5. These methods involve the reaction of Ru.sub.3 (CO).sub.12 or Os.sub.3 (CO).sub.12 with a neutral ligand in a solvent system having a boiling point higher than that of benzene at atmospheric pressure.
