Abstract

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.
