N2 - Ruthenium piano-stool complexes incorporating the new bidentate aminoalkylphosphine ligand 1,2-bis(dipyrrolidin-1-ylphosphino)ethane (dpyrpe, I) or its monodentate counterpart bis(pyrrolidin-1-yl)methylphosphine (pyr 2PMe, II) have been prepared, [(C 5R 5)RuCl(PP)] (R = Me and PP = dpyrpe, 1; R = Me and PP = (pyr 2PMe) 2, 2; R = H and PP = dpyrpe, 3). Complexes 2 and 3 have been characterized by X-ray crystallography. Complexes 1 and 2 react with NaBAr 4 f in the presence of ligand L to yield [Cp*Ru(L)(dpyrpe-κ 2P)] [BAr f 4] (L = MeCN, 4a; CO, 4b; N 2, 4c) and [Cp*Ru(L)(pyr 2PMe) 2][BAr 4 f] (L = MeCN, 5a; CO, 5b; N 2, 5c). Complex 4a was crystallographically characterized. The CO complexes 4b and 5b were examined using IR spectroscopy in an attempt to establish the electron-donating capabilities of I and II. Complex 1 oxidatively adds H 2 in the presence of NaBAr 4 f to yield the Ru(IV) dihydride [Cp*RuH 2(dpyrpe- κ 2P)][BAr 4 f], 7.
