| 英文摘要 | a new water-soluble ruthenium hydride complex [ru(h)-(bpy)(2)(pta)]pf6 (bpy = 2,2'-bipyridine, pta = 1,3,5-triaza-7-phosphaadamantane) (1a) was prepared. 1a reacted with co2 and cs2 to give the corresponding formate and dithioformate complexes, respectively. both the insertions of co2 and cs2 into the ru-h bond of 1a followed second-order kinetics. the second-order rate constant (k(2)) of co2 insertion reaction varied from (9.40 +/- 0.41) x 10(-4) m-1 s(-1) in acetone to (1.13 +/- 0.08) x 10(-1) m-1 s(-1) in methanol; moreover, the ln(k(2)) is in good linear relationship with the acceptor number (an) of the solvent used. although, the k(2) of cs2 insertion reaction ranged from (3.43 +/- 0.10) m-1 s(-1) in methanol to (24.0 +/- 0.5) m-1 s(-1) in n,n-dimethylformamide, which is 1000 times faster than co2 insertion. generally, the k(2) of cs2 insertion increased with the static dielectric constant (d-s) of the reaction medium investigated. for comparison purposes, we further investigated the reactivity of [ru(h)(bpy)(2)(pph3)]pf6 (pph3 = triphenylphosphine) (1b) with co2 and cs2. 1b reacted with co2 slowly in the methanol with a k(2) of (1.46 +/- 0.09) x 10(-3) m-1 s(-1), yielding a formate complex [ru(eta(1)-oc(h)=o)(bpy)(2)(pph3)]pf6 (2b). the reaction of 1b with cs2 is 1000 times faster than that of co2. the structures of 1a, 1b, and 2b were determined by x-ray crystallographic analysis. |
