摘要：

By treatment with excess NaSR (R = i-Pr, Et, Cy, Bz, Ph; Bz = benzyl, Cy = cyclohexyl), [Cp*RuCl2]2(Cp* = η5-C5Me5) gave paramagnetic diruthenium complexes [Cp*Ru(μ-SR)3RuCp*] in moderate yields. An X-ray analysis of [Cp*Ru(μ-S-i-Pr)3RuCp*] disclosed the dinuclear structure with three bridging thiolate ligands. Crystal data: C29,H51S3Ru2, monoclinic, space group p21/a; a = 17.850 (9), b = 10.974 (4), c = 17.320 (13) Å; β = 112.56 (4)°; Z = 4. The Ru-Ru bond distance observed is 2.968 (2) Å, indicating the presence of a relatively long Ru-Ru bond. These complexes (R = i-Pr, Cy) reacted with CO or t-BuNC to give paramagnetic diruthenium complexes [Cp*Ru(SR)(μ-SR)2RuCp*(L)] (R = i-Pr, L = CO, t-BuNC; R = Cy, L = CO), whereas treatment with H2gas or PhC≪CH afforded diamagnetic diruthenium complexes [Cp*RuR′(μ-SR)2RuCp*R′] (R = i-Pr, R′ = H, C≪CPh; R = Cy, R′ = H). © 1990, American Chemical Society.
