A meta-selective-C-H alkenylation of phenol-derivatives employing a traceless organosilicon template

Chem Commun (Camb). 2017 Dec 12;53(99):13209-13212. doi: 10.1039/c7cc07093d.

Abstract

A traceless organosilicon template-directed meta-selective-C-H alkenylation of phenols was realized with good yields and high selectivities. The template was readily removable through F--promoted O-Si cleavage under extremely mild conditions or recyclable through a p-TSA catalyzed process. The product was successfully applied in the preparation of a series of meta-alkenylated aromatic compounds.
