Bond scission over formation: When tertiary carboxylic acids are reacted, a retro-Koch reaction occurs instead of ketonic decarboxylation (see scheme). For the latter, experimental results further support a mechanism that proceeds via the β-keto acid intermediate. The primary retro-Koch product helps to resolve controversial reports on the reaction because it allows the proposal of reasonable pathways to secondary obtained products.

通过酮基脱羧从羧酸形成酮：叔羧酸的特殊情况

断裂导致的断裂：当叔羧酸反应时，发生逆向Koch反应，而不是酮基脱羧反应（请参见方案）。对于后者，实验结果进一步支持了通过β-酮酸中间体进行的机理。最初的Retro-Koch产品有助于解决有关该反应的有争议的报道，因为它允许提出通往次要产品的合理途径的建议。
