eta(3)-Allyliridium(III) complexes Cp*Ir(eta(3)-CHPhCHCH2)(-C=C-t-Bu) (2), Cp*Ir(eta(3)-CHPhCHCH-CH=CH(t-Bu))Cl (3H), Cp*Ir(eta(3)-CHPhCHCH-CH=CMe(t-Bu))I (3Me), [Cp*Ir(eta(3)-CHPhCHCH-CH=CMe(t-Bu))(NCMe)(+) (4), and Cp*Ir(eta(3)-CHPhCHCH-CH=CMe(t-Bu))(-C=C-t-Bu') (5) have been prepared from the reactions of [Cp*Ir(eta(3)-CHPhCHCH2)(NCMe)(+) (1) with H-C=C-t-Bu tin the presence of NEt3), HCl, and Mel. The crystal structures of 2 and 5 have been determined by X-ray diffraction data analyses. Reactions of 3 and 5 with HCl produce trans,trans-1,3-pentadienes, PhCH=CHCH=CHCH2(t-Bu) (6H) and PhCH=CHCH=CHCHMe(t-Bu) (6Me), and cis,trans,trans-1,3,5-heptatriene, (t-Bu')CH=CHC(Ph)=CHCH=CHCHMe(t-Bu) (8), respectively.
