Abstract
Simple, cheap, and toxicologically benign iron salts turned out to be highly efficient precatalysts for cross-coupling reactions of alkyl or aryl Grignard reagents, zincates, or organomanganese species with aryl and heteroaryl chlorides, triflates, and even tosylates. Aryl bromides and iodides are prone to a reduction of their C-X bonds in the presence of the iron catalyst. The exceptionally mild reaction conditions tolerate a series of functional groups such as esters, ethers, nitriles, sulfonates, sulfonamides, thioethers, acetals, alkynes, and -CF3 groups.
