Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), Computed Properties of C41H35ClP2Ru.
The triruthenium cluster with bridging ethanethiolato and indenyl ligands [(eta5-C9H7)Ru(mu-SEt)]3 (2) was synthesized by heating the mononuclear indenyl complex [(eta5-C9H7)Ru(SEt)(PPh3) 2] (1a) in toluene. Cluster 2 reacted with MeI to afford the S-methylated cluster [(eta5-C9H7)3Ru 3(mu-SEt)2(mu-SEtMe)]I·CH2Cl 2 (4a) with high stereoselectivity through the attack of MeI on the axial SEt group from the equatorial side. The PF6- salt of the cationic cluster [(eta5-C9H7)3Ru 3(mu-SEt)2(mu-SEtMe)][PF6] was further converted into the cationic carbonyl complex [(eta5-C9H7)2Ru 2(mu-SEt)(CO)4][PF6] (5) by treatment with CO at 50C. The crystal structures of 4a and 5 were determined by X-ray diffraction study. When a THF solution of 2 was allowed to contact with atmospheric pressure of CO at room temperature, the trinuclear carbonyl cluster [(eta5-C9H7)3Ru 3(mu-SEt)3(mu-CO)(CO)] (6) and the dinuclear carbonyl complex [(eta5-C9H7)Ru(mu-SEt)(CO)]2 (7) were obtained. The structures of 6 and 7 were also crystallographically determined. Furthermore, cluster 2 was oxidized in refluxing CHCl3 to give [(eta5-C9H7)Ru(SEt)Cl]n (9). The Cp analogue of 2, [CpRu(mu-SEt)]3, failed to react with CO and CHCl3, and the hapticity change of the indenyl ligand in 2 is considered to be crucial for the initial interaction of 2 with CO and CHCl3. These reactions provide rare examples of the indenyl ligand effect in a multinuclear complex.
