Abstract

The complexes trans-[Ru(dppm)₂(CCPh₂] and trans-[Ru(LL)₂ CCRCC]_n^- [LL = bis-diphenylphosphino)methane (dppm) or bis-(diphenylphosphino)ethane (dppe), R = p-C₆H₄ or p-C₆H₂(CH₃) ₂] have geen prepared by the reaction of the corresponding trans-[Ru(LL)₂Cl₂] compound with Me₃SnCCPh or Me₃SnCCRCCSnMe₃. Reactions between cis-[Ru(LL)₂Cl₂], acetylenes and the salt NaPF₆ have yielded complexes of the type [CI(LL)₂RuCCPhH]⁺PF₆^-. These were converted into the corresponding mono-acetylides, [Ru(LL)₂Cl(CCPh)] by treatment with 1,8-diazabicyclo[5.4. Ojundec-7-ene(DBU) or alumina. Ale single crystal X-ray structure of [Ru(dppe)₂Cl(CCPh)] confirms that during the reaction of the cis-dihalide species rearrangement takes place to give trans products.
