Abstract

Reaction of CIIr(PEt₃)3 with potassium 2,4-dimethylpentadienide yields the iridacyclohexadiene complex, [ IrCH=C(Me)CH=C{Me)CH₂] (PEt₃)₃(H) (1), by irid-ium-centered activation of a pentadienyl C-H bond. Treatmentof 1 withCH₃Q₃SCF₃produces methane and {[IrCH=C(Me)CH==C(Me)CH₂](PEt₃)₃} ⁺0₃SCF₃- (2), in which one of the ring double bonds coordinates to Jr. Both 1 and 2 have been structurally characterized. Above 0 °C, 2 decomposes in solution to[(tj5-1,3-di-methylcyclopentadienyl)ir(pet3)2(h)]+0₃SCF₃' (3). Treatment of 1 with CH₃I or 2 with NMe₄I yields [IrCH=C(Me)CH=C(Me)CH₂](PEt₃)₃(I) (4).
