Tripodal indolyl phosphine ligands, P(X1PR2)3 (1, 2; X = 3-methyl-1,2-indolediyl; R = Ph, iPr) and P(X2PPh2)3 (3, X2 = 3-methyl-2,1-indolediyl) were prepared by lithiation and phosphination of 3-methylindole; crystal structures, catalytic activity and reactivity of Cu(I), Rh(I) Rh(II) complexes of 1-3 were explored. The high-yielding synthesis and detailed characterization of two well-defined, linkage isomeric tripodal, tetradentate all-phosphorus ligands 1-3 is described. Coordination to Cu(I) resulted in formation of complexes [CuCl[P(X1PR2-κP)2(X1PR2)-κP]] (4, 5, R = Ph, iPr) and [CuCl[P(X2PR2-κP)2(X2PR2)-κP]] (6), for which the mol. structures indicate overall tridentate coordination to the copper atom in the solid state, with one dangling peripheral phosphine. The solution studies suggest fast exchange between the three phosphine side-arms. These new CuI complexes 4-6 catalyze cyclopropanation of styrene with ethyldiazoacetate (EDA), yielding Et 2-phenylcyclopropanecarboxylate with 70:30 trans:cis-selectivity. The anticipated well-defined tetradentate coordination in a C3-sym. fashion was achieved with RhI and IrI, leading to the overall five-coordinated complexes [MCl[P(X1PR2-κP)3-κP]] (7, 9, M = Rh, Ir), [MCl[P(X2PR2-κP)3-κP]] (8, 10, M = Rh, Ir), [Rh(L)[P(X1PR2-κP)3-κP]][BF4] (11, 12, L = η2-norbornadiene, CO). Complex 11 has the norbornadiene (nbd) ligand coordinated in an unprecedented monodentate 2,3-η2 mode to Rh. Furthermore, unexpected but very interesting redox-chem. and reactivity was displayed by the Rh(Cl)-complexes 7 and 8. Oxidation resulted in the formation of stable RhII metalloradicals [7]PF6 and [8]PF6 that were characterized by x-ray crystallog., magnetic susceptibility measurements, cyclic voltammetry, and ESR spectroscopy. Subsequent redox-reactivity of these metalloradicals toward mol. hydrogen is described, resulting in the formation of RhIII hydride compounds
