摘要：

While (Ph2CN2)B(C6F5)(3) is unstable, single electron transfer from Cp*Co-2 affords the isolation of stable products [Cp*Co-2][Ph2CNNHB(C6F5)(3)] 1 and [Cp*Co(C5Me4CH2B(C6F5)(3))] 2. The analogous combination of Ph2CN2 and BPh3 showed no evidence of adduct formation and yet single electron transfer from Cp*Cr-2 affords the species [Cp*Cr-2][PhC(C6H4)NNBPh3] 3 and [Cp*Cr-2][Ph2CNNHBPh3] 4. Computations showed both reactions proceed via transient radical anions of the diphenyldiazomethane-borane adducts to effect C-H bond activations.
