Popis: The synthesis and metalation of two bis(phosphine)/dihydrosilyl ligands at rhodium(I) sources is reported. Irrespective of the substitution at silicon (diaryl versus diamino), multiple Si–H activations and chloride migration afford tridentate bis(phosphine)/chlorosilyl complexes of Rh(I). For the diarylsilyl ligand, reaction with a cationic rhodium(I) triflate precursor gives the analogous triflatosilyl complex. The [P2Si]H2 proligands and their Rh complexes provide distinct opportunities for exploring metal/silicon cooperative reactivity.
