摘要

摘要研究了芳基乙炔在环境电氧化条件下高效、环保地合成芳基羧酸的方法。在乙腈和水的混合溶液中，以过氧单硫酸氢钾(氧酮)为添加剂，在一定的施加电位下，反应顺利进行。分离产物的收率可达90%以上，反应具有良好的官能团耐受性。在这种电化学系统中，不需要过渡金属催化剂、额外的酸/碱和高温。该方法为电化学合成羧酸开辟了新的途径。

Synthesis of Aryl Carboxylic Acids through Ambient Electro-oxidation of Arylacetylenes

Abstract An efficient and environment-friendly synthesis of aryl carboxylic acids through the ambient electro-oxidation of the arylacetylenes is demonstrated. The reaction proceeds smoothly at certain applied potentials in a mixed solution of acetonitrile and water with potassium peroxymonosulfate (Oxone) as the additive. The isolated yields of the desired products are good up to 90%, and the reaction exhibits excellent functional-group tolerance. In this electrochemical system, transition metal catalysts, extra acids/bases, and high temperature are not required. This method may open up a pathway for the synthesis of carboxylic acids by the electrochemistry strategy.
