The intermolecular C–S bond cleavage takes place in 4a promoted by MeI to form [Ru(I)(η1-C2H3)(depe)(PMe3)2] 5 with liberation of MeSPh. On the other hand, reactions of 1 with vinyl carboxylates in the presence of tertiary phosphines such as PMe3, PEt3 or depe give a series of (η1-vinyl)ruthenium(II) complexes cis-[Ru(η1-C2H3)(η1-OCOR′)(PMe3)4]
