  • Patent number: 6534666
    Abstract: This invention relates to an improvement in a purification process for producing those liquid copper based complexes of &bgr;-diketones and, particularly the monovalent copper complexes of &bgr;-diketones, which are suited for application by chemical vapor deposition in the electronics industry. In the basic process for preparing a copper based complex, a reactive copper compound is reacted with a fluorinated &bgr;-diketonate and an organo source such as an olefinic source or one having acetylenic unsaturation. Purification is effected by contacting reaction product with a double deionized deoxygenated water source and preferably an acid/water source. An aqueous layer and an organic layer are formed with the aqueous layer containing byproducts and the organic phase containing product.
