Abstract

Terminal organotransition-metal acetylides trans-[Pt(C≡CR)2L2] (R = Ph or But, L = PPh3 or PEt3), cis-[Pt(C≡CBut)2L2] (L = PPh3 or PEt3), [Pt(C≡CR)2(dppe)] (R = But or SiMe3, dppe = Ph2PCH2CH2PPh2) and [Au(C≡CR)(PPh3)] (R = Ph or But) reacted with cis-[Pt(C6F5)2(CO)(thf)] (thf = tetrahydrofuran) to give, under alkynylation of the fragment Pt(C6F5)2(CO), the μ-η2-acetylide-bridged dinuclear zwitterionic complexes [(OC)(C6F5)2Pt-(μ-η 2-C≡CR)M+Ln]. The phenylacetylide complex [(OC)(C6F5)2Pt-(μ-η 2-C≡CPh)Pt+(C≡CPh)(PPh3) 2] has been characterised by X-ray structural analysis.
