The novel Pd(0)-azobenzene complex (ITMe)2Pd(PhN═NPh) (5) (ITMe = 1,3,4,5-tetramethylimidazol-2-ylidene) has been isolated and characterized in the solid state and by cyclic voltammetry. Its reactivity toward E–E′ bonds (E, E′ = Si, B, Ge) has been compared with that of the known carbene complex (ITMe)2Pd(PhC≡CPh) (2). Whereas 2 reacts with all E–E′ bonds studied, 5 only reacted with B–B and B–Si moieties, echoing our previous catalytic studies on azobenzenes.
