Synthesis of Pd3Tl and Pd6Tl2 Complexes Based on a Trinuclear Aryl-Palladium(II) Complex Acting as a Metallaligand Toward Thallium(I) Through Tl-Arene and Tl-I Bonds
The metallaligand [(PdIL2)(3)(C6Me3-1,3,5)] (L-2 = 4,4'-di-tert-butyl-2-2'-bipyridine = tbbpy) reacts with TIOTf to afford the complex [{(PdIL2)(3)C6Me3-1,3,5}Tl]OTf, which exists in the solid state as a 2:1 mixture of monomer and dimer, both showing Tl(I)-I and Tl(I)-eta(6)-mesitylene bonds. In solution, only the monomer is observed. Heating of toluene solutions of [(PdIL2)(3)(C6Me3-1,3,5)] affords the dinuclear complex [(PdIL2)(2)(C6HMe3-1,3,5)].
