The first examples of direct introduction of PhSe and N3 functions by addition to olefins are reported. The addition of PhSeN3 to simple alkenes, as well as to activated alkenes takes place in the absence of a catalyst. The reaction proceeds stereospecifically but not regiospecifically, apparently via a 3-membered selenonium ion intermediate.
报道了通过添加烯烃直接引入PhSe和N 3官能团的第一个实例。在没有催化剂的情况下,将PhSeN 3加到简单的烯烃以及活化的烯烃中。该反应显然是立体定向的,而不是区域特异性的,显然是通过一个三元硒离子中间体进行的。
