method for the phosphonyl C2,C3C bond formation under the free radical, reductive conditions is described. The new approach is based on the synthesis of novel 2- and 3- phosphonyl radicals 6, 9 derived from the corresponding 2- and 3-halo (XCl, Br, I) substituted phosphonates 7, 10 and their reaction with alkenes 4. Functionalized phosphonates 5, 8 possessing the 2+2 and 3+2 elongated carbon chain were
为膦酰基C A一般方法2,C 3自由基,在还原条件下C键形成进行说明。这种新方法是基于新颖的合成2-和3-膦酰基6,9从相应的2-和3-卤代衍生(XCl,溴,I)取代的膦酸酯7,10和它们与烯烃反应4。官能膦酸酯5,8具有的2 + 2和3 + 2细长的碳链在24÷73%的产率获得。
