A cascade-transmetallation sequence allows a one-pot conversion of arylsilanes into functionalized arylcoppers; they react with various types of electrophiles (allylic halides, acid chlorides, bromoalkynes); bimetallic zincâcopper-reagents can be prepared by this method either directly or in a sequential fashion.
通过级联-反金属化顺序,可将芳基硅烷一次性转化为功能化芳基铜;它们可与各种类型的亲电物(烯丙基卤化物、酸性氯化物、溴炔)发生反应;双金属锌铜试剂可通过这种方法直接或依次制备。
