(9) This question demonstrates the use of osmium tetroxide to oxidize alkenes. OsO4 bonds two of its oxygen atoms to the same side of the double bond. When this intermediate is cleaved by Na2SO3 in aqueous solution, the resulting product is a cis-1,2-diol. The osmium tetroxide will not react with the aromatic ring, just with the lone, separate double bond in the ring on the right side of the molecule. Therefore, when you draw the ...
This solution provides explanations for drawing products of reactions and determining what alkenes are needed to make a dialdehyde.
