In a 100 mL beaker, add 0.5 g of finely powdered hydrated copper(II) sulfate, 2.5 g of triphenylphosphine, and 40 mL ethanol. Heat and stir until all of the triphenylphoshine and most of the CuSO4is dissolved. Remove the solution from heat and then carefully and slowly add 0.5 g of sodium borohydride (caution: the reaction with effervesce and you should allow the bubbling after each addition to subside before adding more borohydride). Filter the solution under suction to isolate the crude product. Dissolve this crude product in 15 mL of methylene chloride and then gravity filter the solution into a 50 mL beaker. Rinse the residue with a minimal amount of methylene chloride. Heat the methylene chloride solution in a boiling hot water bath. While the methylene chloride is evaporating, slowly add 25 mL of ethanol. When the total volume has reduced to ~30 mL, remove the solution from the hot water bath and allow the solution to cool to ambient temperature. Filter the resulting mixture and wash the crystalline residue (your product) with ethanol. Dry the product under vacuum. Obtain an IR spectrum of your product. Also, obtain an IR spectrum of triphenylphosphine as a reference.
