Bis(2,2′-bipyridyl)copper(II) Permanganate is prepared by Potassium Permanganate (0.01 mol) dissolved in a minimum of water is added to bis(2,2′-bipyridyl)copper(II) chloride (0.02 mol) in water (25 mL). On cooling a purple precipitate is collected and air dried.2 The yield is 95%.
Oxidant, store in a glass vessel at or below rt. The reagent should be filtered and dried on a filter paper, not on a sintered glass funnel. It should be transferred with nonmetallic spatulas; if metallic spatulas are used the reagent may burst into flame.
