The stericeffects of substituents on five-memberedrings are less pronounced than those on six-membered rings because of the difference in bond angles. Thus, the regioselectivities of reactions of five-membered heteroarenes that occur with selectivities dictated by stericeffects, such as the borylation of C-H bonds, have been poor in many cases. We report that the silylation of five-membered-ring
