Regioselective aromatic C-H silylation of five-membered heteroarenes with fluorodisilanes catalyzed by iridium(I) complexes.
The aromatic C-H silylation of five-membered heteroarenes with 1,2-di-tert-butyl-1,1,2,2-tetrafluorodisilane regioselectively proceeded at 120 degrees C in octane in the presence of a catalytic amount of iridium(I) complexes generated from 1/2[Ir(OMe)(COD)]2 and 2-tert-butyl-1,10-phenanthroline.

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.
متن کاملRemarkably selective iridium catalysts for the elaboration of aromatic C-H bonds.
Arylboron compounds have intriguing properties and are important building blocks for chemical synthesis. A family of Ir catalysts now enables the direct synthesis of arylboron compounds from aromatic hydrocarbons and boranes under "solventless" conditions. The Ir catalysts are highly selective for C-H activation and do not interfere with subsequent in situ transformations, including Pd-mediated...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
