ABSTRACT Fluorinated .beta.-ketoimine ligands and highly volatile .beta.-ketoiminato metal complexes of the ligands are synthesized by silylatlng a fluorinated .beta.-dike- tone to form a sllylenolether, and subsequently reacting the silylenolether with a primary diamine to form the desired ligand having the structural formula: Image wherein R1, R2, R4 and R5 are independently linear or branched per- fluorinated, C1-C8 alkyl groups and R3 is any organic functionality such as a C1-C8 alkylene, phenylene or hydroxyalkylene group, all of which can be partially or fully fluorinated. The corresponding metal complex is formed by treatlng the ligand with a metal halide.
