Fluorinated beta-ketoiminato metal complexes.

摘要

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 diamine to form the desired ligand having the structural formula: <CHEM> wherein R1, R2, R4 and R5 are independently linear or branched perfluorinated, 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 treating the ligand with a metal halide.
