Reductive Preparation of Fluoroalkyl Copper Complexes from Perfluorinated Alkyl Iodides Using Diboron

Area of Science:

• Organometallic Chemistry
• Fluorine Chemistry

Background:

• Fluoroalkylated arenes are important building blocks in pharmaceuticals and materials science.
• Efficient methods for introducing fluoroalkyl groups are highly sought after.

Purpose of the Study:

• To develop a novel reductive synthesis of fluoroalkyl copper phenanthroline complexes.
• To utilize these complexes for mild and efficient cross-coupling reactions with aryl iodides.

Main Methods:

• Reductive synthesis of copper complexes using fluoroalkyl iodides and diboron.
• Structural characterization of the copper complex via X-ray crystallography.
• Cross-coupling reactions between copper complexes and aryl iodides.

Main Results:

• Successfully synthesized and characterized a novel fluoroalkyl copper phenanthroline complex.
• Demonstrated smooth cross-coupling of the copper complex with aryl iodides under mild conditions, yielding fluoroalkylated arenes.
• Developed a one-pot protocol for direct reductive coupling of aryl and fluoroalkyl iodides.

Conclusions:

• The reported method provides an efficient route to fluoroalkylated arenes.
• The developed copper complexes and one-pot protocol offer practical advantages for fluoroalkylation.
