New tricks for an old dog: The Pd‐catalyzed carbonylative α‐arylation of monoethyl potassium malonates with aryl bromides and reactive aryl chlorides provides a simple and direct route to aryl β‐ketoesters. Because only stoichiometric amounts of carbon monoxide are employed, the method is ideal for the introduction of carbon isotopes into more complex structures.
老狗的新招数:丙二酸单乙酯钾的Pd催化羰基α-芳基化与芳基溴化物和反应性芳基氯化物的合成提供了一条简单而直接的途径制备芳基β-酮酸酯。由于仅使用化学计量的一氧化碳,因此该方法非常适合将碳同位素引入更复杂的结构中。
