Application of 32993-05-8. Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II)
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, [(C5R5)RuCl(PP)] (R = Me and PP = dpyrpe, 1; R = Me and PP = (pyr2PMe)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 NaBAr4f in the presence of ligand L to yield [Cp*Ru(L)(dpyrpe-kappa2P)] [BArf4] (L = MeCN, 4a; CO, 4b; N2, 4c) and [Cp*Ru(L)(pyr2PMe)2][BAr4f] (L = MeCN, 5a; CO, 5b; N2, 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 H2 in the presence of NaBAr4 f to yield the Ru(IV) dihydride [Cp*RuH2(dpyrpe- kappa2P)][BAr4f], 7.
