selective ortho-C(sp2)–H silylation of aromatic ketones has been achieved using an aminooxyamide auxiliary. The reaction tolerates various orth-, meta-, and para- substituents on the aromatic ring and can be applied to thiophenyl and vinylketones. The ortho-C(sp2)–H bond was monosilylated selectively in comparison with other aromatic C–H bonds, benzyl or allylic C(sp3)–H bonds, and acidic α-C(sp3)–H bonds
