Abstract

The progress in catalytic organic synthesis with iridium was far behind that with rhodium or palladium in the early 1990s. However, many useful reactions have recently been reported, and iridium catalysts have now been recognized to be useful in organic synthesis. This review covers iridium-catalyzed carbon-carbon and carbon-heteroatom bond formation with particular emphasis on useful reactions for organic synthesis.
