An efficient procedure for the synthesis of 1,1-diacetates from aldehydes with acetic anhydride catalyzed by silica sulfate

摘要

The reaction of aldehyde with acetic anhydride catalyzed by silica sulfate results in 1,1-diacetates in high yields at room temperature.The protection of aldehydes by formation of 1,1-diacetates is of great importance in synthetic organic chemistry because of the stability of corresponding products and easy conversion into parent aldehydes.
