Nucleophilic attack by H ⊖ at the complex cation 1 , which contains a π‐bonded thiophene derivative, leads to breakage of a CS bond and formation of the neutral butadienethiolate complex 2 . Analogous reactions are also possible with other nucleophiles and complexes with other substituted thiophene ligands. In contrast, in the case of complexes containing Mn instead of Ru, the CS bonds remain intact. These findings could help to give a better mechanistic understanding of the catalytic hydrodesulfurization of crude oil.
