Platinum Oxide Catalyzed Silylation of Aryl Halides with Triethylsilane

Significance

Arylsilanes are useful intermediates in organic synthesis, which might be used, for instance, as nucleophiles in aryl-aryl cross-coupling as well as in a number of other transition-metal-catalyzed coupling reactions. The search for a direct route toward these compounds from aryl halides, avoiding too reactive aryllithium or -magnesium intermediates attracts recently significant attention. So far, such a transformation has been successfully performed only on electron-rich aryl iodides, using Pd as catalyst. This method is complementary with the previously described protocols, and covers a larger scope of the substrates, including those bearing highly susceptible functional groups like nitro or aldehyde.
