Facile single or double C-H bond activation on η 2-platinum-complexed acetylenes by interaction with [cis-PtR 2S2] and [cis-PtR2(CO)S] (R = C 6F5, S = Thf)

The μ-hydride μ-acetylide [cis,cis-(PPh3) 2Pt(μ-H)(μ-1κCα:η 2-C≡CPh)Pt(C6F5)2] (1b) and the μ-vinylidene [cis,cis-(CO)(C6F5) 2Pt(μ-C=CHPh)Pt(PPh3)2] (2) have been prepared by reaction of the η2-phenylacetylene Pt(0) complex [Pt(η2-HC≡CPh)(PPh3)2] as the starting material with the disolvated [cis-PtR2S2] and the monosolvated [cis-PtR2(CO)S] (R = C6F5, S = tetrahydrofuran) complexes, respectively. Extension of these reactions to the μ-η2:η2-bis-(alkyne)diplatinum(O) precursor [{Pt(PPh3)2}2-{1,4-HC≡C) 2C6H4}] and 2 equiv of the corresponding solvated complexes affords the bis(μ-hydride) μ-diethynylbenzene [{cis,cis-(PPh3)2Pt(μ-H)Pt(C6F 5)2}2{μ-1κCα:4kC α′:η2:η 2-(1,4-C≡C)2C6H4}] (4b) and the bis(μ-vinylidene) [{cis,cis-(CO)(C6F5) 2PtPt(PPh3)2}2{μ 4-1κCα:2κC α:3κCα′:4κC α′-(1,4-C=CH)2C6H4}] (3)tetranuclear derivatives. The preparation of the isomeric [{trans-(PPh 3)(C6F5)Pt(μ-H)Pt(C6F 5)-(PPh3)}2{μ-1κC α:4κCα:η2:η 2-(1,4-C≡C)2C6H4}] (4a) was achieved by reaction of ({trans-PtH(PPh3) 2}{μ-1κCα:2 κC α′-(1,4-C≡C)2C6H 4}] with 2 equiv of [cis-PtR2S2]. Single-crystal X-ray structural determinations of 1b, 2, 3, and 4b are reported.

Synthesis and structure of new neutral bimetallic platinum hydride complexes

The reactions of mononuclear hydride complexes trans-[PtHXL2] with the solvated species Cis-[Pt(C6F5)2(thf)2] constitute a simple methodology to high-yield synthesis of dinuclear compounds with a mixe
