C,C- and C,N-Chelated Organocopper Compounds.

Area of Science:

• Organic Chemistry
• Organometallic Chemistry

Background:

• Copper-catalyzed reactions and organocopper intermediates are vital in organic synthesis.
• Understanding the structure-function relationship of organocopper compounds is essential for designing new reactions and reagents.

Purpose of the Study:
