Synthesis and characterization of new urthenium (II) complexes containing diisopropylmethylphosphine

摘要

The reaction between RuCl_3 and P~iPr_2Me in 2-methoxyethanol yielded the five-co-ordinate complex [RuCl_2(CO)(P~iPr_2Me)_2] in which the phosphine groups show a cisoid arrangement. The co-ordination sphere of the ruthenium nucleus can be completed with neutral ligands such as CO, ~tBuNC, Hpz, 3, 5-dimethylpyrazole and HN=CPh_2. Likewise, it reacts with S-donor reagents like PhSH and @-surfanylpyridine and readily undergoes metathesis reactions with salts of some chelating ligands like NaS_2CNEt_2, KS_2COR (R = Me, Et, or ~iPr) and K (acac) which are bonded in a bidentate mode.
