Palladium complex morningside
WebPalladium dimethylsilanedithiolato complex is a precursor for Ti Pd and Ti Pd 2 heterometallic complexes. 311 The bis-silyl sulfides (R 3 Si) 2 S have been widely used to prepare a variety of metal sulfide clusters, because these reagents exploit the strength of the Si O and Si Cl bond to replace a halide, alkoxide, acetate, or oxide with a sulfido ligand …
