“…In recent years, a variety of directing groups have been used to control the regioselectivity of CH bond silylation 8. 9 For example, imine,8a,e oxazoline,8c,i pyridine,8d,f,i,j, 9a,b pyrazole,8d,g and tertiary amine8d functionalities have been used as directing groups for the silylation of aromatic and benzylic CH bonds with trialkylsilanes. However, these directing groups are usually undesired in the final product, and multiple chemical transformations are needed to install and remove them.…”
