Single Electron Transfer to Diazomethane–Borane Adducts Prompts C−H Bond Activations

While (Ph(2)CN(2))B(C(6)F(5))(3) is unstable, single electron transfer from Cp*(2)Co affords the isolation of stable products [Cp*(2)Co][Ph(2)CNNHB(C(6)F(5))(3)] 1 and [Cp*Co(C(5)Me(4)CH(2)B(C(6)F(5))(3))] 2. The analogous combination of Ph(2)CN(2) and BPh(3) showed no evidence of adduct formation a...

description While (Ph(2)CN(2))B(C(6)F(5))(3) is unstable, single electron transfer from Cp*(2)Co affords the isolation of stable products [Cp*(2)Co][Ph(2)CNNHB(C(6)F(5))(3)] 1 and [Cp*Co(C(5)Me(4)CH(2)B(C(6)F(5))(3))] 2. The analogous combination of Ph(2)CN(2) and BPh(3) showed no evidence of adduct formation and yet single electron transfer from Cp*(2)Cr affords the species [Cp*(2)Cr][PhC(C(6)H(4))NNBPh(3)] 3 and [Cp*(2)Cr][Ph(2)CNNHBPh(3)] 4. Computations showed both reactions proceed via transient radical anions of the diphenyldiazomethane–borane adducts to effect C−H bond activations.
