The performance of potassium permanganate and hydrogen peroxide oxidation and/or alum coagulation in the removal of complexed FE(II) from drinking water
The influence of solution pH, DOC concentration, the relative molecular weight distribution of DOC, and the source of DOC were investigated for their effects on the removal of complexed Fe(II) by alum coagulation and/or KMn04 and H20 2 oxidation. The differentiation between particulate, colloidal, …

Reactivity studies of arene-cis-diols in cycloadditions and potassium permanganate oxidations: synthesis of the corresponding arene-trans-diols and an approach to the synthesis of (+)-pancratistatin
Potassium permanganate oxidations and novel cycloaddition chemistry of the arene-cis-diols (7) were investigated. It was found that permanganate oxidation of arene-cis-diols yielded a mixture of 2 products, (157a) and (157b) in low yield. The influence of the C1-substituent on the outcome of the …
