Reactions of an Anionic Gallylene with Azobenzene or Azide Compounds Through C(sp²)-H and C(sp³)-H Activation.

ABSTRACT: The activation of inert C-H bonds remains a challenge in current chemistry. Here, we report the excellent reactivity of the anionic gallylene species [LGa:][Na(THF)₃] (L = [(2,6-iPr₂C₆H₃)NC(CH₃)]₂^2-, 1) that allows the selective activation one ortho sp² C-H bond of several azobenzene and azide derivatives at ambient temperature, with the transfer of the hydrogen atom to one of the nitrogen atoms. The process leads to the formation of the aryl amido products [LGa-κ²N,C-PhNN(H)(p-R-C₆H₃)][Na(solvent)₃] (2, R = H solvent = DME (1,2-Dimethoxyethane); 3, R = -OMe, solvent = DME; 4, R = -NMe₂ solvent = THF)
