Abstract
The reaction of [{Ru( η 5-TMT)( μ-Cl)Cl} 2] (TMT=tetramethylthiophene) with the thioether ligand [9]aneS 3 (1,4,7-trithiacyclononane) gives a new cationic sandwich complex [Ru( η 5-TMT)( κ 3-[9]aneS 3)] 2+. Reaction of this complex with ethoxide gives the complex ion [Ru( η 4-C 4Me 4S-2-OEt)( κ 3-[9]aneS 3)] + in which the carbon at the ‘2’ position on the thiophene ligand is attacked but otherwise the ring remains intact and coordinates to the metal in an η 4 fashion, as confirmed by the X-ray structure determination of [Ru( η 4-C 4Me 4S-2-OEt)( κ 3-[9]aneS 3)][PF 6].
