醋酸锰引发产生的膦自由基与α,β-不饱和砜的反应

Manganese(Ⅲ)-Mediated Alkenyl C(sp^2)—P Bond Formation from the Reaction of α,β-Unsaturated Sulfones with Dialkyl Phosphites

报道了在醋酸锰作用下二烷基亚膦酸酯与α,β-不饱和砜的反应,反应以醋酸为溶剂、80℃条件下反应2 h,以40%~72%的收率得到了烯基膦酸酯衍生物.

Mn（OAc）_3-mediated reaction of dialkyl phosphites with α,β-unsaturated sulfones to form α,β-unsaturated phosphonates is described. This reaction proceeded in acetic acid at 80 ℃ for 2 h to afford selective（E）-2-alkenyl phosphonates in 40%~72% yields.
