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.
