Role of potassium carbonate in sharpless assymetric dihydroxylation?

Answer 1

to keep the pH opf the reaction mass towards basic.

Answer 2

Potassium carbonate is used as a base in Sharpless asymmetric dihydroxylation to maintain the alkaline conditions necessary for the reaction to proceed efficiently. It helps in neutralizing any acid byproducts formed during the reaction, thus preventing side reactions that could interfere with the desired product formation. Additionally, potassium carbonate helps to control the pH level, which is crucial for achieving high enantioselectivity in the dihydroxylation process.
