Abstract
The reaction of the monophosphido-bridged diruthenium(III) complex [Cp*RuCl(μ-PMe2)(μ-Cl)RuClCp*] with sodium hydrogen sulfide affords the hybrid phosphido- and hydrosulfido-bridged diruthenium(III) complex [Cp*RuCl(μ-PMe2)(μ-SH)RuClCp*]. The hydrosulfido-bridged diruthenium(III) complex can be further converted into the corresponding sulfido-bridged multinuclear ruthenium(III) complex via deprotonation of the hydrosulfido ligand. The hydrosulfido-bridged diruthenium(III) complex also reacts with bases to afford a coordinatively unsaturated diruthenium(III) complex, where insertion of terminal alkynes further occurs to form phosphido-bridged diruthenium(III) complexes bearing ruthenathiacyclobutene moieties.
