Aromatic C-H silylation of neat arenes with 1-hydrosilatrane was found to be efficiently catalyzed by iridium catalysts composed of 1/2[Ir(OMe)(cod)] 2 and 2,9-dimethyl-1,10-phenanthroline at 120 °C to afford the corresponding silylated products in high yields. The silylated products can be used for the Hiyama cross-coupling reaction.
