  Butenynyl and Vinylidene Complexes of Ruthenium

  摘要：

  Reaction of ruthenium bis-acetylide complexes with 2,6-lutidinium tetrafluoroborate gave butenynyl complexes cis-[Ru(eta(3)-RC CC=C(H)R)(PMe(3))(4)]BF(4) in moderate to good yields. The structure of cis[Ru(eta(3)-tBuC CC=C(H)tBu)(PMe(3))(4)]BF(4) was determined crystallographically. Attempts to prepare cis[Ru(eta(3)-MeC CC=C(H)Me)(PMe(3))(4)]BF(4) resulted in the formation of two isomers, which differ in the stereochemistry about the double bond. The reaction of two bis-acetylide complexes with methyl triflate afforded butenynyl-type complexes cis- [Ru(eta(3)-RC CC=C(Me)R)(PMe(3))(4)](+) (R = Me, Ph). The mixed acetylide-vinylidene complex trans-[Ru(C CSiMe(3))(C=CH(2))(PMe(3))(4)]PF(6) was prepared by the reaction of trans-Ru(C CSiMe(3))(2)(PMe(3))(4) with ammonium hexafluorophosphate. In addition, the crystal structure of trans-[Ru(C CH)(C=CH(2))(PMe(3))(4)]BF(4) is reported.

  Terminal acetylenes react with cis-RuMe2(PMe3)4 to form the bis(acetylido) complexes cis/trans-Ru(C≡CR)2(PMe3)4 in good yield. The structures of trans-2 (R = Ph), cis-3 (R = p-C6H4-OMe), trans-4 (R = p-C6H4-Me), cis-6 (R = Me), trans-7 (R = SiMe3) and cis-8 (R = H) were determined by X-ray crystallography.
