Manufacturing process for producing a β copper diketone complex

Claim 2

A process for producing a β copper diketone complex which consist of the steps: (a) mixing and reacting Cu 2 O, 1,1,1,5,5,5-Hexafluoro-2, 4-pentanedione and an additional cuprous L, an electronic donator; and (b) dehydrating the crude material of step (a).

Claim 3

The process of claim 1 wherein in step (b) a dehydrating agent is used for dehydrating the crude material.

Claim 4

The process of claim 1 wherein the additional cuprous L, an electronic donator, is selected from the group consisting of (I), (II), (III) and (IV) wherein (1) R 1 .tbd.R 2 [R 1 and R 2 are hydrocarbon radicals with 1-8 carbon atoms or organic radicals with 1-8 carbon atoms consisting Si.]; (2) R 3 (R 4 ) (R 5 ) [R 3 , R 4 and R 5 are hydrogen atoms or hydrocarbon radicals with 1-6 argon atoms.]; (3) Ring hydrocarbon with 5-18 carbon atoms, which may have more than two double bonds. (4) R 6 (R 7 ) (R 8 )Si--(CH 2 ) n --C(R 9 )═CR 10 (R 11 ) (R 6 , R 7 , R 8 , R 9 , R 10 , R 11 are hydrogen atoms, hydrocarbon radicals with 1-6 carbon atoms, or organic radicals with 1-6 carbon atoms constituting Si. " n " ═0 , 1, or 2.).

Claim 5

The process of claim 1 wherein after step (b) the following step is added: (c) purifying of the crude material in a column chromatogram filled with at least one filling agent selected from the group consisting of silica gel and alumina.

Claim 6

The process of claim 2 wherein the dehydrating agent is selected from one of the groups consisting of copper sulfate, sodium sulfate, magnesium sulfate and molecular sieves.

Claim 7

The process of claim 4 wherein the filling agent for the column is dehydrated.

Claim 8

The process of claim 4 wherein the column contains two or more layers of the dehydrating agents.
