Copper(II) acetate hydrate (Cu(OOCCH3)2•xH2O)-Powder

Characteristic

Copper(II) acetate, also referred to as cupric acetate, is the chemical compound with the formula Cu(OAc)₂ where AcO− is acetate (CH₃CO⁻²). The hydrated derivative, which contains one molecule of water for each Cu atom, is available commercially. Anhydrous Cu(OAc)₂ is a dark green crystalline solid, whereas Cu₂(OAc)₄(H₂O)₂ is more bluish-green.

Application

Copper(II) acetate monohydrate is used in formation of Cu chelates of ß-dicarbonyl compounds as a means of purification and in the eglinton (modified glaser) coupling of terminal alkynes. It is also used as a catalyst for the michael reaction giving increased yields and absence of side-reactions. It Promotes ullmann-type C-O and C-N coupling reactions of arylboronic acids with phenols, amines and various other nitrogen derivatives. It is also used in biochemical applications such as DNA extraction.
