资源简介：
New η3-silane σ-complexes [PhBPPh3]RuH(η3-H2SiRR′) (RR′ = PhMe, Ph2) were synthesized. Lewis bases [THF, 4-(dimethylamino)pyridine, and PMe3] coordinate to the silicon centers of these complexes to form stable adducts. The base adducts, [PhBPPh3]Ru(μ-H)3SiRR′(base), feature three nonclassical Ru–H–Si interactions and hexacoordinate silicon centers, as determined by multinuclear NMR spectroscopy, X-ray crystallography, and computational investigations.
