A Dinuclear Ir(III) Bis(thiophosphinite) Complex Formed by Unusual meta-C–H Activation at a Pincer Ligand

Oxidative addition of PC(H)P pincer ligands at late transition metals typically occurs via C–H activation in the 2-position of the ligand, yielding [(PCP)MHX] type pincer complexes (X = monoanionic ligand). We present formation of the dinuclear Ir(III) complex [(iPrPSCSPiPr)Ir(H)(MeCN)2]2[OTf]2 as a rare example of meta-C–H activation at a pincer ligand.
