  A method for preparing an aliphatic chloroformate comprising, introducing a mixture of at least one aliphatic hydroxyl compound, phosgene, at least one solvent, and optionally at least one organic base into a flow reactor to obtain a unidirectional flowing reaction mixture. The at least one aliphatic hydroxyl compound comprises at least one aliphatic hydroxyl group. The unidirectional flowing reaction mixture is maintained at a temperature between about 0° C. and about 60° C. to produce a single product stream comprising an aliphatic chloroformate.

• Cerium(IV) induced hydroxylation of c-alkylated hydrocarbons and phenols

  DOI：10.1016/s0040-4020(01)85902-0

  日期：1988.1

  Hydroxylation of C-alkylated phenols has been achieved by employing cerium (IV) ammonium nitrate and hydrogen peroxide in acetic acid medium. The yield of hydroxylation products increases markedly when 3 × 10-3 M solution of sodium dodecyl sulphate is added to the oxidation system. The plausible mechanism of the reaction seems to involve free radical intermediates and is influenced by hydrophobic environment

  通过在乙酸介质中使用硝酸铈（IV）铵和过氧化氢，可以实现C烷基化苯酚的羟基化。当将3×10 -3 M十二烷基硫酸钠溶液添加到氧化系统中时，羟基化产物的产率显着增加。该反应的合理机制似乎涉及自由基中间体，并且受疏水环境的影响。从酚的氧化偶联的观点来看，该发现也具有重要意义。
