Synthesis and properties of [Ru(tpy)(4,4'-X2bpy)H]+ (tpy = 2,2':6',2-terpyridine, bpy = 2,2'-bipyridine, X = H and MeO), and their reactions with CO2

A novel type of hydrido complex [Ru(tpy)(4,4'-X2bpy)H]+ (X = H and MeO) was synthesized. The stronger hydridic character of the complexes compared with [Ru(bpy)2(L)H]+ type complexes (L = CO, PPh3 and AsPh3) was demonstrated by the relatively high chemical shifts of Ru-H in the 1H NMR spectra a...

description A novel type of hydrido complex [Ru(tpy)(4,4'-X2bpy)H]+ (X = H and MeO) was synthesized. The stronger hydridic character of the complexes compared with [Ru(bpy)2(L)H]+ type complexes (L = CO, PPh3 and AsPh3) was demonstrated by the relatively high chemical shifts of Ru-H in the 1H NMR spectra and by higher reactivities with CO2. The reactions of [Ru(tpy)(4,4'-X2bpy)H]+ with CO2 occurred at second-order rate constants varying from (4.69 ± 0.02) to (5.51 ± 0.04) x 10-3 M-1 s-1 depending on both solvent and X, giving the formato complexes [Ru(tpy)(4,4'-X2bpy)(OCHO)]+ quantitatively.
