Applications

Zinc-copper couple is used in the Simmons-Smith cyclopropanation reaction, Reformatsky reaction. It is used as a chemical for the selective, stereospecific reduction of alkynes to cis-alkenes. It is used in for deiodination of iodotributylstannylalkanes. In the presence of a free-radical initiator, it promotes the formylation of perfluoroalkyl iodides with DMF to give fluorinated aldehydes in high yield. It is used in dermatology.

Notes

Store at 4°C. Moisture Sensitive. Do not store together with acids. Protect from humidity and water. Incompatible materials are amines, cadmium, chlorinated solvents, Sulfur compounds.
