Abstract

<jats:title>Abstract</jats:title> <jats:p>Ligand exchange of [RuH2(CO)(PPh3)3] with some diphosphine ligands affords a series of [RuH2(CO)(diphosphine)(PPh3)] (diphosphine = dppe, dppp, dppb, and dppf). The X-ray structure analysis of [RuH2(CO)(dppp)(PPh3)] reveals its distorted octahedral structure. The diphosphine ligand complexes react with styrene to generate ruthenium(0) species, which successively proceed with the intramolecular C-H addition to give the cyclometallated aryl(hydrido)ruthenium(II) species.</jats:p>
