The first aromatic C−H silylation between arylphosphines and hydrosilanes enabled by a ruthenium complex has been developed. The excellent ortho ‐selectivity results from a four‐membered metallacyclic intermediate involving phosphorus chelation. The developed system can be extended to the benzylic C−H silylation of arylphosphines. Diverse silylated arylphosphines are produced, exhibiting broad functional

coupling of a hydrodisilane with alcohols is reported. During the reaction, the SiSi bond is preserved effectively when [RuCl2(p-cymene)]2 is used as a catalyst. Various alcohols can be used in this alkoxylation.
