✦ Synopsis

instead give products Cp * IrClCH 2 C(=NHAr)CMe=N(Ar) + Cl -in which the dab ligand has undergone C-H activation at one of methyl groups of the dab bridge. The C-H cleavage reaction is reversible in the sense that thermally, the cyclometalated Ir complex decomposes to regenerate the free ligand.
