and acidity but also on the acid used. When hydrolyzed at 65° C by certain strong monobasic acids of high molecular weight the amide and the peptide.
acid-catalyzed hydrolysis of amides when conducted at low. [H30+] 7. Herein we report that two typical amides
Base-Promoted Hydrolysis of Amides at Ambient. Temperatures. Sir: Often one is presented with the problem of hydrolyzing amides which are acid sensitive and
This is interpreted in terms of an AoT2 mechanism of amide hydrolysis acid-catalyzed hydrolysis of amides there are.
Even though acids can promote amide hydrolysis base catalysis is generally more efficient.1 In a number of studies on aliphatic amides
