The first aromatic C-H silylation between arylphosphines and hydrosilanes enabled by ruthenium complex has been developed. The excellent ortho-selectivity was resulted from a four-membered metallacyclic intermediate involving phosphorus chelation. The developed system could be extended to benzylic C-H silylation of arylphosphines. Diverse silylated arylphosphines are produced, which exhibit broad functional group compatibility. Further functionalization of the products under mild conditions renders the formed compounds
