Physical Data: Cu(OAc)2·H2O: mp 115 °C (dec 240 °C); d 1.882 g cm−3. FeSO4·7H2O: forms tetrahydrate at 56.6 °C, monohydrate at 65 °C, loses last H2O at about 300 °C and dec at higher temperatures; d 1.897 g cm−3. Solubility: Cu(OAc)2·H2O: sol H2O and alcohol; slightly sol ether and glycerol. FeSO4·7H2O: sol H2O; very slightly sol alcohol. Form Supplied in: Cu(OAc)2·H2O: dark green solid; widely available. FeSO4·7H2O: blue-green solid; widely available. Preparative Methods: the reagents are prepared individually as saturated solutions in methanol and used directly. Generally, the substrate is mixed with methanolic copper acetate and to this is added a methanolic solution of iron sulfate. Handling, Storage, and Precautions: aqueous solutions of FeSO4 are oxidized by air. Use in a fume hood.
