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.


Chemical formula:Cu(CH3COO)2

Molar mass:181.63 g/mol 

Appearance:Dark green crystalline solid

Melting point:Undetermined

Boiling point:240 °C (464 °F; 513 K)

Solubility in water:7.2 g/100 mL (cold water);20 g/100 mL (hot water)

Solubility:Soluble in alcohol;Slightly soluble in ether and glycerol

Refractive index (nD):1.545 


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.
