Aromatic organosilanes bearing C(sp2)–Si bonds have found increasing applications across the chemical science, yet are mostly produced by atom-uneconomical stoichiometric procedures. Catalytic alternatives using hydrosilanes as silicon sources have also been described, but they display unfavorable thermodynamics and are mostly based on expensive catalytic systems, often derived from noble metals, or

a little does the trick! The catalytic enantioselective arylation using chiral dicationic palladium complexes provides a reliable and useful access to enantiomerically enriched mandelic‐acid derivatives. Significantly low catalyst loading (down to 0.002 mol %) as well as easy catalyst handling are the advantage of this practical method.

Chemical modification of aromatic polyphenyl ethers by silylation (trimethylsilyl, dimethylphenylsilyl, methyldiphenylsilyl and siloxanyl groups), has been investigated and shown to give products with improved low-temperature fluidity without change of thermal stability.
