The unprecedented radical β-elimination of vinylsulfoxides opens a new access to functionalized di- and trisubstituted allenes. The radical precursors are obtained in two steps from a carbonyl derivative and a vinylsulfoxide. The radical translocation trick can also be used to trigger the β-elimination of the sulfinyl radical.
前所未有的乙烯基亚砜自由基β消除为官能化的二取代和三取代的亚丙基开辟了新途径。自由基前体是由羰基衍生物和乙烯基亚砜分两步获得的。自由基易位技巧也可用于触发亚磺酰基自由基的β消除。
