Open the CIPO recordAbstract From the Canadian patent
Fluorinated .beta.-ketoimine ligands and highly volatile .beta.-ketoiminato metal complexes of the ligands are synthesized by silylating a fluorinated .beta.-diketone to form a silylenolether and subsequently reacting the, silylenolether with a primary amine to form the desired ligand having the structural formula:, wherein R1 and R2 are independently linear or branched perfluorinated C1-C8 alkyl groups and R3 is any organic functionality such as a C1-C8 alkyl, phenyl or hydroxyalkyl group all of which can be partially, or fully fluorinated. The corresponding metal complex is formed by treating the ligand with 3 metal halide.
