English abstract Syntheses of some ruthenium(II) complexes containing 2-chloro-1,3,2-dioxaphospholane and 2-chloro-4,5-benzo-1,3,2-dioxaphospholane are reported for the first time. The reaction of dichloro-tris(triphenylphosphane)ruthenium(II) with these ligands always leads to formation of a product containing two molecules of dioxaphospholane, independently of the stoichiometric proportion employed. On the other hand, complexes derived from chloro(cyclopentadienyl) bis (triphenylphosphane)ruthenium(II) have only one ligand in their structure. The complexes were characterized by 31P{¹H} and ¹H-NMR spectroscopy

As reações do dicloro-tris(trifenilfosfino)rutênio(II) com os ligantes em questão produziram sempre um complexo contendo duas moléculas de dioxafosfolano, independente da estequiometria empregada. Já os complexos derivados do cloro(ciclopentadienil)bis(trifenilfosfino)rutênio(II) têm apenas um ligante em sua estrutura. Os complexos foram caracterizados por RMN de 31P{¹H} e ¹H
