Azametallametallocene Formation via Double sp(3) C-H Activation of 6-Substituted ortho-Toluidines by a Half-sandwich Acetatoiridium Complex
A half-sandwich acetatoiridium(III) complex can activate two geminal C(sp(3))-H bonds of 2-methylaniline derivatives to produce a new dinuclear azametallacycle, (eta(5)-1,2,3,4,5-penta-methylcyclopentadienyl) [eta(5)-2-(eta(5)-1,2,3,4,5-pentamethylcyclo-pentadienyl)iridaindolyl]iridium. The C-N chelate iridium displaying an amido-carbene structure favors formation of the saturated 34 electron complex via pi-coordination to the other [Cp*Ir] fragment.
