A simple procedure for the synthesis of a variety of o-carboxyarylacrylic acids has been developed with Oxone (2KHSO5·KHSO4·K2SO4); the oxidation reaction involves the stirring of methoxy/hydroxy-substituted naphthalenes, phenanthrenes, anthracenes, etc. with Oxone in an acetonitrile–water mixture (1:1, v/v) at rt. Mechanistically, the reaction proceeds via initial oxidation of naphthalene to o-quinone
已经用Oxone(2KHSO 5 ·KHSO 4 ·K 2 SO 4)开发了一种简单的合成多种邻-羧基芳基丙烯酸的方法。氧化反应包括在室温下将乙氧基/羟基取代的萘,菲,蒽等与Oxone在乙腈-水混合物(1:1,v / v)中搅拌。从机理上讲,该反应是通过将萘初始氧化为邻醌而进行的,该邻苯醌会裂解成相应的邻羧基芳基丙烯酸。发现高级芳族化合物产生衍生自最初形成的邻-羧基芳基丙烯酸的羧甲基内酯。
