Elimination of sulfur from aromatic heterocycles by a water-soluble arene ruthenium cluster: synthesis and molecular structure of [H_2S_2Ru_4(C_6H_6)_4]Cl_2

摘要

C-S bond cleavage in thiophene, benzothiophene and dibenzo-thiophene is achieved under biphasic conditions by the water-soluble cluster cation [H_4Ru_4(C_6H_6)_4]~(2+) which is converted into the disulfido cluster [H_2S_2Ru_4(C_6H_6)_4]~(2+).
