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

So the key to a decarboxylation reaction is having a cabonyl beta to a carboxylic acid. So, for example, here's our carboxylic acid, and we know the carbon next to a carboxylic acid is the alpha carbon, and the carbon next to that is the beta carbon, and we saw how this carbonyl was necessary in the mechanism. And so the fact that there's an OH ...
