20.11 DECARBOXYLATION OF CARBOXYLIC ACIDS

20.11 DECARBOXYLATION OF CARBOXYLIC ACIDS 977 This reaction, which also does not occur in base, bears a close resemblance to the decarboxy-lation of b-keto acids because both malonic acids and b-keto acids have a carbonyl group bto the carboxy group. Because decarboxylation of malonic acid and its derivatives requires heating, the acids

3.2.4 Decarboxylation. The decarboxylation of mercury (II) carboxylates to give organomercury compounds (Equation (14)) can be brought about thermally or with free radical initiation. (14) The thermal reaction occurs when R, which can be an alkyl or alkenyl, or aryl group, carries electron-withdrawing substituents.
