Mild deacetylation of 1,3-dicarbonyl compounds was achieved by halonium-ion mediated electrolysis. In this reaction, the supporting electrolyte including sodium halide NaX (X = Cl or Br) was essential since the reaction proceeded through substitution by a halonium ion, generated electrochemically at anode, on active methine carbons followed by base-catalyzed deacetylation, and was terminated by reductlve dehalogenation of the formed α-halo carbonyl compounds at cathode.
通过卤锪离子介导的电解,成功实现了1,3-二羰基化合物的温和去乙酰化。在此反应中,支持电解质的包含钠卤化物NaX(X = Cl或Br)是至关重要的,因为反应通过阳极电化学生成的卤锪离子在活性次甲基碳上的取代进行,紧接着是碱催化的去乙酰化,并在阴极通过还原脱卤终止于形成的α-卤代羰基化合物。
