Secondary alcohols having a carbonyl group at the neighboring carbon atom were electrochemically oxidized to the corresponding α-keto carbonyl compounds in good yields. Thus, aromatic α-hydroxyl esters were easily transformed to arylglyoxylates in excellent yields using an undivided cell while efficient anodic oxidation of α-hydroxyl ketones and aliphatic α-hydroxyl esters successfully proceeded in a divided cell to give the corresponding α-keto carbonyl compounds.
邻位碳原子上具有羰基的二级醇在电
化学氧化条件下顺利转化为相应的α-酮羰基化合物,产率良好。因此,芳香族α-羟基酯在未分隔的电池中可以轻松转化为芳基
乙二酸酯,产率极高,而α-羟基酮和脂肪族α-羟基酯在分隔的电池中经过高效的阳极氧化也成功转化为相应的α-酮羰基化合物。
