The reactions of [Pd(E-R)Cl(tmeda)] [R = C6H(E-CH=CHPh)-6-(OMe)3-2,3,4; tmeda = N,N,N′,N′-tetramethylethylenediamine] with Tl(CF3SO3) and CH≡CH, PhC≡CPh, or PhC≡CH selectively give compounds [Pd(η-Ind)(tmeda)]CF3SO3 [Ind = 1-benzyl-5,6,7-trimethoxyindenyl (2), 1-benzyl-2,3-diphenyl-5,6,7-trimethoxyindenyl (3), 1-benzyl-3-phenyl-5,6,7-trimethoxyindenyl (4)]. When a mixture of [Pd(E-R)Cl(bipy)] (bipy = 2,2′-bipyridine) and [Pd(Z-R)Cl(bipy)] is reacted with Tl(CF3SO3) and MeC≡CMe, the complex [Pd(η-Ind)(bipy)]CF3SO3 [1-benzyl-2,3-dimethyl-5,6,7-trimethoxyindenyl (5)] is obtained. The structures of 3 and 4 have been determined by X-ray studies at 203 and 173 K, respectively. According to the structural data for 3 and 4, the hapticity of the indenyl ligands is intermediate between η3-and η5-coordination.
