Germylene-beta-sulfoxide Hemilabile Ligand in Coordination Chemistry
We describe herein the synthesis of a germylene-beta-sulfoxide ligand, 1, and its abilities in coordination chemistry. Treatment of 1 with metal complexes [W(cod)(CO)(4)], [Mo-(nbd)(CO)(4)] and [Ni(cod)(2)] afforded the corresponding (1)chelated metal complexes (1)-W(CO)(4)(2a), (1)-Mo(CO)(4)(2b), and (1)-Ni(cod) (4a), clearly showing a bidentate ligation of the metal by the germanium(II) and sulfur centers. Coordination with [Ru(PPh3)(3)Cl-2] afforded an unprecedented bridged bis(ruthenium) complex 3b. In the case of 4a, the hemilability of the bidentate ligand 1 was demonstrated by sulfoxide substitution by a CO ligand.
