See reaction of alkene with naio4 and kmno4. Groups that are trans on the alkene will end up trans on the cyclopropane product. Over-oxidation to the carboxylic acid is not a problem. C OC H 3. Check also: reaction and reaction of alkene with naio4 and kmno4 12In the previous post we learned that the anti-dihydroxylation of alkenes is achieved by converting them not epoxides followed by acid or base-catalyzed ring-opening of the ring.
Looking at the equation purely from the point of view of the organic reaction. Balancing the reactions would involve using the methods learned in general chemistry requiring half reactions for all processes.

In presence of potassium permanganate it undergoes oxidation to form acetone and acetic acid.
3Mild oxidising conditions are present when the oxidising agent is a cold room temperature alkaline solution OH -aq of potassium permanganate KMnO 4 The mild oxidation of alk-1-enes 1-alkenes produces an alkane-12-diol often just referred to as a diol. In a typical procedure 44 a solution of KMnO 4 7 mg NaIO 4 225 mg and K 2 CO 3 29 mg in 29 mL of 73 t-butyl alcoholwater was added to a solution of alkene 0213 mmol in 2 mL of t -butyl alcohol. The reaction is named after its inventors Raymond Urgel Lemieux and William Summer Johnson who published it. This reaction involves syn addition leading to a cisglycol a vicinal dihydroxy compound. 21Cleavage Of Vicinal Diols By Sodium Periodate NaIO4 The Mechanism. The reaction of alkenes with sodium arene sulfinates in the presence of potassium iodide and sodium periodate and a catalytic amount of acetic acid provides vinyl sulfones at room temperature.
