Elimination of sulfur from aromatic heterocycles by a water-soluble arene ruthenium cluster: synthesis and molecular structure of [H2S2Ru4(C6H6)4]Cl2.
C-S bond cleavage in thiophene, benzothiophene and dibenzothiophene is achieved under biphasic conditions by the water-soluble cluster cation [H(4)Ru(4)(C(6)H(6))(4)](2+) which is converted into the disulfido cluster [H(2)S(2)Ru(4)(C(6)H(6))(4)](2+).
