• Oxidation of alcohols by electrochemically regenerated nickel oxide hydroxide. Selective oxidation of hydroxysteroids
  作者：Johannes Kaulen、Hans-J. Schäfer

  DOI：10.1016/0040-4020(82)80110-5

  日期：1982.1

  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。

  This disclosure provides a process for producing vinylidene dimer derivatives by subjecting one or more vinylidene dimers and one or more carbonyl-containing compounds to a carbonyl-ene reaction, optionally in the presence of a catalyst, to produce one or more vinylidene dimer derived alcohols. This disclosure also provides a process for producing vinylidene dimer derivatives by reacting one or more vinylidene dimers with one or more carbonyl-containing compounds, optionally in the presence of a catalyst, to produce one or more vinylidene dimer derived alcohols. This disclosure further provides vinylidene dimer derivatives (e.g., vinylidene dimer derived alcohols and esters) produced by these processes. This disclosure still further provides for hydrogenating/reacting the vinylidene dimer derived alcohols with acids or anhydrides to produce vinylidene dimer derived esters. This disclosure yet further relates to lubricating ester oil base stocks, and lubricating oils containing the lubricating ester oil base stocks.
