| Abstract | The ruthenium aqua complexes [cp*Ru(OH2)(N-N)](OTf) (cp* = [small eta]5-pentamethylcyclopentadienyl, N-N = 2,2[prime or minute]-bipyridine, phen = 1,10-phenanthroline, OTf- = trifluoromethanesulfonate) and the acetonitrile complex [cpRu(CH3CN)(bipy)](OTf) (cp = [small eta]5-cyclopentadienyl) are water-, acid-, and thermally stable (200 [degree]C) catalysts for the hydrogenation of aldehydes and ketones in sulfolane solution. In the presence of HOTf as a co-catalyst, they effect the deoxygenation of 1,2-hexanediol to 1-hexanol and hexane. Glycerol is deoxygenated to 1-propanol in up to 18% yield and under more forcing conditions completely deoxygenated to propene. The structure of the acetonitrile pro-catalyst [cpRu(CH3CN)(bipy)](OTf) has been determined by X-ray crystallography (space group P[1 with combining macron] (a = 9.3778(10) A; b = 10.7852(10) A; c = 11.1818(13) A; [small alpha] = 101.718(5)[degree]; [small beta] = 114.717(4)[degree]; [gamma] = 102.712(5)[degree]; R = 3.95%). |
