摘要：

Trans-chelating bis(diisopropylphosphino)triptycene (1) was employed as a platform for the construction of a new class of C(sp(3))-metalated pincer complexes via C-H activation. We synthesized and fully characterized platinum(II), ruthenium(II), and iridium(III) compounds hearing this tridentate ligand. In contrast to the known all-aliphatic C(sp(3))-metalated compounds, the new complexes exhibit excellent thermal and conformational stability even under very harsh and noninert conditions, likely due to the lack of labile alpha- or beta-hydrogens. In addition, the three-dimensional barrelene-based scaffold represents a unique structural motif for the design of PC(sp(3))P-based compounds with unexplored steric and electronic features.
