Dihydrogen complexes of ruthenium. 2. Kinetic and thermodynamic considerations affecting product distribution
- Yale Univ., New Haven, CT (USA)
Cationic ruthenium dihydrogen complexes of the form (({eta}-C{sub 5}H{sub 5})Ru(L)(L{prime})({eta}{sup 2}-H{sub 2}))BF{sub 4} (L = CO, L{prime} = PCy{sub 3} (1a), PPh{sub 3} (2a), PMe{sub 2}Ph (3a), PMe{sub 3} (4a) have been prepared by protonation of the corresponding neutral hydrides. Carbonyl free derivatives such as (({eta}-C{sub 5}H{sub 5})Ru(P P{prime})({eta}{sup 2}-H{sub 2}))BF{sub 4} (P P{prime} = 1,2-bis(dimethylphosphino)ethane (dmpe) (5a), (1,1-dimethyl-2,2-diphenylphosphino)ethane (dmdppe) (6a), (R)-(+)-1,2-bis(diphenylphosphino)propane ((R)-prophos) 8a), bis(PPh{sub 3}) (9a)) were similarly prepared. Identification of these species as dihydrogen complexes is based upon observation of substantial H-D coupling (22-32 Hz) in the {sup 1}H NMR spectra of the Hd analogues, prepared by protonation of the corresponding deuterides.
