Cr Nh3 6 3 Oxidation State Of Oxygen
In this case the oxidation tolerated the presence of alkene and carbonyl moieties. Yong Qiang Tu’s synthesis of the Alzheimer’s disease medication galanthamine likewise used this reaction in the presence of an acid-sensitive acetal group. Driggith and Potts Gill Mines worked low temperature lead-zinc-copper veins on the eastern and northern slopes of High Pike. Arsenopyrite is abundant there, and its oxidation in veins that also contain primary lead, zinc and copper sulfides has produced a range of supergene arsenates. [Read More]
