I know that β-ketocarboxylic acids undergo decarboxylation on light heating through an enol intermediate undergoing a pericyclic reaction. However, what other groups may be placed at the β position that may give the same decarboxylation reaction?
I haven't been able to find any reputable sources. However, my teacher gave us a question in which an imine at β position underwent decarboxylation following the same process as a β-ketocarboxylic acid would. Does this reaction happen and are there other groups that follow the exact decarboxylation mechanism when at the β position?
