dibromination of unactivated alkenes and alkynes has been demonstrated by using methyl α-bromoacetate as a mild brominating agent. A near-visible light (370 nm) light-emitting diode (LED) mediates this simple dibromination reaction under mild conditions with the inexpensive and nontoxic α-bromoacetate. The reaction proceeds well with both terminal and internal alkenes and alkynes and those contained
通过使用 α-溴乙酸甲酯作为温和的溴化剂,已证明光诱导未活化的烯烃和炔烃的邻位二溴化。近可见光 (370 nm) 发光二极管 (LED) 在温和条件下利用廉价且无毒的 α-溴乙酸盐介导这种简单的二溴化反应。该反应对于末端和内部的烯烃和炔烃以及N/O-杂环中所含的烯烃和炔烃均进行良好,表明其在合成二溴化有机化合物中的多功能性。
