Reactivity of [Ru₃(CO)₁₂] with Dibenzothiophene, Methylbenzothiophene, and Methyldibenzothiophene

Abstract

The reaction of dibenzothiophene (DBT) with [Ru3(CO)12] in heptane affords the dinuclear complex [Ru2(C12H8)(μ-CO)(CO)5], derived from a double C−S bond activation−desulfurization process. The reaction of this complex with H2 under very mild conditions leads to the release of biphenyl.

“…12), [Ru 2 (CO) 5 (-CO)(-2 -4 -C 6 H 4 ) 2 ] (14) and [Os 2 (CO) 6 (-2 -4 -C 6 H 4 ) 2 ] (15), the Ru and Os analogues 14 and 15 of which have been characterized by X-ray crystallography [15]. The reactions for Fe and Ru can be completed within just a few hours at elevated temperatures (3 h/98 • C and 4 h/126 • C, respectively); however, the Os cluster is much less reactive, with 33% of [Os 3 (CO) 12 (16) in 10% yield after column chromatography ( Fig. 13) [16].…”

The Ru atoms are linked by a Ru-Ru bond (2.6965(9) Å) and a bridging carbonyl, and the structure has been confirmed by X-ray diffraction.…”

“…The solvent was removed under reduced pressure, and the resulting residue was redissolved in a minimal amount of dichloromethane and separated on TLC (eluent: chloroformehexane (70:30 v/v)). The first band, orange, was identified as the known compound [Ru 3 (m-Cl) 2 (CO) 8 …”

“…The first orange band was identified as unreacted [Ru 3 (CO) 10 (m-dppe)] (14 mg, 50%). The second, deep orange band, was assigned to compound [Ru 3 (CO) 8 …”
