Abstract
Treatment of a chelating silane 1-(dimethylsilyl)-2-silylbenzene (4) with Pd(PEt3)4 in the ratio of 2:1 selectively afforded a unique mononuclear palladium complex [{1,2-C6H4(SiMe2)(SiH)}2Pd(PEt3)2] (6), which was formed by two Si–Si coupling reactions between the SiH2 groups and the SiMe2 moieties from two hydrosilane ligands. Complex 6 was structurally characterized by single crystal X-ray analysis and multinuclear NMR spectroscopic studies and is one of the very few examples of cis-bis(silyl)palladium(II) complexes containing in situ formed Si–Si single bonds.
