Increasing steric hindrance in β-keto carboxylic acids leads to an increasing kinetic stability towards decarboxylation, till systems are reached which are completely stable at room temperature. Simultaneously the tautomeric equilibrium is changed in favour of the (Z)-enol, and finally in favour of the (E)-configurated enol.
β-酮基羧酸的空间位阻增加,导致脱羧的动力学稳定性增加,直至达到在室温下完全稳定的体系。同时,改变互变异构平衡以有利于(Z)-烯醇,最后有利于(E)-构型的烯醇。
