Manganese-Mediated Cross-coupling Reactions

Manganese-Catalyzed or -Mediated Cross-coupling Reactions... 

Moreover, copper(l) halides or manganese(ll) bromide efficiently catalysed the Stille reaction of arylstannanes with aryl halides without any palladium catalyst added [87,88]. In contrast to MnBr2, manganese(II) chloride was proved as a less effective catalyst, whereas manganese(II) iodide-mediated reactions failed to give any cross-coupled products [88]. The latter achievements dramatically extend the economy of the Stille reaction since the use of, generally very expensive, palladium chemicals is completely avoided.
