β-dicarbonyl compounds were electrochemically oxidized in a methanolic solution in the presence of sodium cyanide and sodium methoxide to yield the corresponding α-cyano-β-dicarbonyl compounds in moderate to good yields. Presumably, a two-electron transfer transforms the anion derived from the β-dicarbonyl compounds into a cation, which then reacts with a cyanide ion to afford the cyanation products.
在氰化钠和甲醇钠的存在下,几种β-二羰基化合物在甲醇溶液中被电化学氧化,以中等至良好的产率产生相应的α-氰基-β-二羰基化合物。据推测,双电子转移将衍生自 β-二羰基化合物的阴离子转化为阳离子,然后与氰化物离子反应得到氰化产物。
