Meta-Selective C-H Functionalization of Arylsilanes Using a Silicon Tethered Directing Group

Abstract

We describe meta-selective C-H functionalization of arylsilanes using a Si-tethered directing group. The current method enables a selective alkenylation of arenes bearing a variety of functional groups, and several electron-deficient olefins are also applicable as coupling partners. Further functional group transformations of the silicon-tethered directing group provide multi substituted arenes efficiently.
