Primary alcohols, α,ω-diols and secondary alcohols are easily transformed into carboxylic acids, dicarboxylic acids or ketones, respectively, by heterogeneous oxidation with nickel oxide hydroxide electrochemically regenerated at a nickel hydroxyde electrode. The results are discussed in comparison to those of the nickel peroxide and chromic acid oxidation. The oxidation rate decreases with increasing
伯醇,α,ω-二醇和仲醇很容易分别通过在氢氧化镍镍电极上电化学再生的氧化镍氢氧化物进行多相氧化而分别转化为羧酸,二羧酸或酮。与过氧化镍和铬酸氧化的结果进行了讨论。氧化速率随着醇的空间位阻的增加而降低,从而允许羟基甾族化合物中3位的选择性氧化。
