Abstract

The present invention provides methods for the preparation of compounds of the formula (Formula I):LyM(CO)zwherein 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 Ru3(CO)12 or Os3(CO)12 with a neutral ligand in a solvent system having a boiling point higher than that of benzene at atmospheric pressure.
