Complexes of ruthenium halides with organic sulphides (thioethers)
Abstract
Ruthenium trichloride reacts with mono-(S), di-(SS), or tri-sulphides (SSS) to form complexes of the types mer-[RuX3S3], [{RuCl3(SS)1·5}n], and trans-[RuX2(SS)2] or [RuCl3(SSS)]. The compounds have been characterised by analysis, and by i.r., u.v., 1H n.m.r., and e.s.r. spectroscopy. The monosulphides are not strongly bound and can be displaced by pyridine, aniline, or acetonitrile to give [RuCl3(pyridine)3], [RuCl3(PhNH2)3], or [RuCl3(MeCN)3].
Several carbonyl (alkyl sulphide) complexes of ruthenium are reported, and the first abstraction of carbon monoxide from solvent by a sulphide complex. Attempts to use some of the complexes as hydrogenation catalysts were not successul.
