The first molybdenum-catalyzed allylic sulfonylation of tertiary allylic electrophiles is described. The method employs a readily accessible catalyst (Mo(CO)6/2,2′-bipyridine, both are commercially available) and represents the first example of the use of a group 6 transition metal-catalyst for allylic sulfonylation of substituted tertiary allylic electrophiles to form carbon–sulfur bonds. This atom
描述了第三级烯丙基亲电试剂的第一钼催化的烯丙基磺酰化。该方法采用易于获得的催化剂(Mo(CO)6 / 2,2'-联吡啶,均可商购),并且是使用第6组过渡金属催化剂进行取代的叔烯丙基亲电子试剂的烯丙基磺酰化的第一个实例。形成碳硫键。这种原子经济且操作简单的方法,其特点是相对温和的条件,较宽的底物范围和出色的区域选择性,因此即使在后期功能化的情况下,也可以开辟一个新的平台来锻造砜部分,并为进一步衍生化提供了充足的机会通过传统的铃木交叉偶联反应。
