Metalloradical Reactivity of Ru(I) and Ru(0) Stabilized by an Indole‐Based Tripodal Tetraphosphine Ligand

The tripodal, tetradentate tris(1‐(diphenylphosphanyl)‐3‐methyl‐1H‐indol‐2‐yl)phosphane PP(3)‐ligand 1 stabilizes Ru in the Ru(II), Ru(I), and Ru(0) oxidation states. The octahedral [(PP(3))Ru(II)(Cl)(2)] (2), distorted trigonal bipyramidal [(PP(3))Ru(I)(Cl)] (3), and trigonal bipyramidal [(PP(3))Ru...

Sumario:The tripodal, tetradentate tris(1‐(diphenylphosphanyl)‐3‐methyl‐1H‐indol‐2‐yl)phosphane PP(3)‐ligand 1 stabilizes Ru in the Ru(II), Ru(I), and Ru(0) oxidation states. The octahedral [(PP(3))Ru(II)(Cl)(2)] (2), distorted trigonal bipyramidal [(PP(3))Ru(I)(Cl)] (3), and trigonal bipyramidal [(PP(3))Ru(0)(N(2))] (4) complexes were isolated and characterized by single‐crystal X‐ray diffraction, NMR, EPR, IR, and ESI‐MS. Both open‐shell metalloradical Ru(I) complex 3 and the closed‐shell Ru(0) complex 4 undergo facile (net) abstraction of a Cl atom from dichloromethane, resulting in formation of the corresponding Ru(II) and Ru(I) complexes 2 and 3, respectively.
