fully characterised in solution. Also, the mechanism of the C–H oxidative addition has been elucidated by DFT calculations showing that the square planar iridium(I) complexes of the formula [IrClx(SiNP)P(OMe)3}2−x](1−x)+ (x = 0, 4+; x = 1, 7) should be firstly obtained from 2+ and finally should undergo the C–H oxidative addition to iridium(I) via a concerted intramolecular mechanism.
