Development of more labile low electron count Co( i ) sources: mild, catalytic functionalization of activated alkanes using a [(Cp*Co) 2 -μ-(η 4 :η 4 -arene)] complex

Catalytic transfer dehydrogenation of silyl protected amines, requiring sp(3) C-H bond activation, is mediated by a bridging arene complex of the type [(Cp*Co)(2)-μ-(η(4):η(4)-arene)] under mild conditions. Mechanistic and qualitative rate studies establish the compound as a more reactive Co(I) source when compared to other known Cp*Co(I) complexes.
