Abstract

We describe herein the synthesis of a germylene-β-sulfoxide ligand, , and its abilities in coordination chemistry. Treatment of with metal complexes [W(cod)(CO)], [Mo(nbd)(CO)] and [Ni(cod)] afforded the corresponding ()-chelated metal complexes ()-W(CO) (), ()-Mo(CO) (), and ()-Ni(cod) (), clearly showing a bidentate ligation of the metal by the germanium(II) and sulfur centers. Coordination with [Ru(PPh)Cl] afforded an unprecedented bridged bis(ruthenium) complex . In the case of , the hemilability of the bidentate ligand was demonstrated by sulfoxide substitution by a CO ligand.

摘要

我们在此描述了一种亚锗烯-β-亚砜配体的合成及其在配位化学中的能力。用金属配合物[W(环辛二烯)(CO)]、[Mo(降冰片二烯)(CO)]和[Ni(环辛二烯)]处理该配体，得到了相应的( )-螯合金属配合物( )-W(CO) ( )、( )-Mo(CO) ( )和( )-Ni(环辛二烯) ( )，清楚地表明了锗(II)和硫中心对金属的双齿配位。与[Ru(PPh)Cl]配位得到了一种前所未有的桥连双(钌)配合物。在的情况下，通过CO配体取代亚砜证明了双齿配体的半活性。
