A novel and metal catalyst-free synthesis of aryloxyacetamides from the corresponding arylboronic acids and 2-bromoacetonitrile promoted by alkaline solutions of hydrogen peroxide has been developed involving an oxidation-reduction of eco-friendly H2O2 with simultaneous reaction ipso-hydroxylation of arylboronic acid and hydration of the nitrile. This protocol is compatible with sensitive substituents
开发了一种由相应的芳基硼酸和 2-溴乙腈在过氧化氢碱性溶液促进下合成芳氧基乙酰胺的新型无金属催化剂合成方法,涉及环保型 H2O2 的氧化还原反应以及芳基硼酸的同羟基化反应和水合反应腈。该协议与连接到芳基硼酸的敏感取代基兼容,并在纯水中以中等到良好的收率提供所需的产品。
