Substitution reactions of chloro(η5-cyclopentadienyl)bis( triphenylphosphine)-ruthenium(II) with some thiocarboxa(i)mides

Abstract Reactions of [(η 5 -C 5 H 5 )RuCl(PPh 3 ) 2 ] with the ligands of the type RCSNHCOOC 2 H 5 (R = 2-pyrrole, 2-thiophene or 4-toluene), RCSNHCONHC 6 H 5 (R = 2-pyrrole) and 2-thiopyrrole-1,2-dicarboximide lead to the formation of diamagnetic compounds of the formula [(η 5 -C 5 H 5 )RuCl(PPh 3 )(ligand)]. These compounds were characterised by using analytical, magnetic, conductivity and spectroscopic (UV, VIS, IR and proton NMR) data. A distorted octahedral geometry is proposed for the complexes.
