| الوصف: | The reaction of the propargylic salt [Ph3PCH2C≡CH]PF6 with [Pt(C2H4)(PPh3)2] affords the η2-allenylphosphonium salt [Pt(η2-CH2═C═CHPPh3)(PPh3)2]PF6 via a metal-mediated propargylic rearrangement. Isomerization of the complex occurs in solution to generate the salt [Pt{η2-C(PPh3)═C═CH2}(PPh3)2]PF6, wherein the allene is coordinated by the internal C═C bond. Computational studies indicate that the isomerization of the propargylic cation [Ph3PCH2C≡CH]+ to the allenyl species [Ph3PCH═C═CH2]+ and the α-alkynyl isomer [Ph3PC≡CCH3]+ is thermodynamically favorable. The isomeric η2-alkynylphosphonium salt [Pt{η2-C(CH3)≡CPPh3}(PPh3)2]PF6 is formed from the reaction of [Ph3PC≡CCH3]PF6 with [Pt(C2H4)(PPh3)2] and does not isomerize to the propargylic or allenyl forms. |
