    Decarboxylation was first encountered in. Oxidative decarboxylation of carboxylic acids. Another useful method for generating O (76%> aM) acid in pyridine solution in presence. Formation of. Decarboxylation is a chemical reaction that removes a carboxyl group and releases carbon dioxide (CO2). Usually, decarboxylation refers to a reaction of carboxylic acids, removing a.
    Both intermediates involve protonation of the alpha carbondisrupting one of the double bonds of the aromatic ring and permitting the beta-keto group which takes the form of an enol in THCA and THC to participate in decarboxylation.

    This is conceptually the same as the more general term "decarboxylation" as defined above except that it specifically requires that the carboxyl group is, as expected, replaced by a hydrogen.
