A mild and practical oxyarylation of alkenes by oxidative radical addition has been developed by using aerobic oxidation of hydrazine compounds. The use of a catalytic amount of potassium ferrocyanide trihydrate (K4[Fe(CN)6]⋅3 H2O) and water accelerated this radical reaction to give peroxides or alcohols from simple alkenes in good yields. The environmentally friendly and economical radical reactions
通过使用肼化合物的需氧氧化,已经开发了通过氧化自由基加成的烯烃的温和而实用的氧化芳基化反应。催化量的三水合亚铁氰化钾(K 4 [Fe(CN)6 ]⋅3H 2 O)和水的使用加速了这种自由基反应,从而以良好的收率从简单的烯烃制得过氧化物或醇。在室温下,在铁催化剂,氧气和水的存在下,实现了环保,经济的自由基反应。还描述了一种涉及苯胺作为自由基前体的方法。
