A radical coupling reaction of diverse vinyl sulfones and epoxides was mediated by Cp2TiCl (Cp = cyclopentadienyl) to provide a straightforward synthetic pathway to hydroxy sulfones. The reaction was successfully achieved by using either an excess or a catalytic amount of the TiIII reagent. The scope of the reaction was studied for several different functionalized and substituted epoxides and vinyl
多种乙烯基砜和环氧化物的自由基偶联反应由 Cp2TiCl(Cp = 环戊二烯基)介导,以提供直接合成羟基砜的途径。通过使用过量或催化量的 TiIII 试剂成功地实现了反应。对几种不同的官能化和取代的环氧化物和乙烯基砜的反应范围进行了研究。
