hello,

I attached my question:

thanks..

[discodermolide]

What is the product when H₂O₂ is used?

[helper]

they both. It depends on whetere the attack is upper or beneath the molecule.
My question is if we use NaHSO4 we will get other products?

thank you ahead.

[discodermolide]

The NaHSO₃ is there to quench excess peroxide.

[helper]

thank you.
So it has no influence on the products, right?

[discodermolide]

Nope.

[helper]

sorry but I don't understand your answer can you please rephraise yourself?

[discodermolide]

The NaHSO₃ is there to quench excess peroxide and has no influence upon the reaction product.

[helper]

thank you !!

This has been awkwardly illustrated. Generally, OsO4 is only used in a catalytic amount. Peroxides are used to oxidize the osmium intermediates back to OsO4. Then after the oxidation is complete, it is as disco suggested, bisulfate removes the peroxides.

I only wanted to clarify this as the poster asked about the bifulfite, but had not illustrated the osmium oxidation with peroxide.
