摘要:
A process for the vapor-phase synthesis of non-adduct volatile fluorinated and non-fluorinated metal-ligand complexes comprising contacting a .beta.-diketone or .beta.-ketoimine ligand with an inert carrier gas to vaporize the ligand, reacting the vaporized ligand with a metal species at a temperature sufficient to form the metal-ligand complex and recovering the metal-ligand complex by sublimation. The process is conducted in the absence of solvent thereby providing pure non-adduct metal-ligand complexes. Such complexes are particularly suited for specialty applications requiring use of high purity compounds.
