Abstract
En 中文
The 1 : 2 reaction of the imidazole-based dithiolate (2) with GeCl2 center dot dioxane in THF/TMEDA gives 3, a TMEDA-complexed dithiolene-based germylene. Compound 3 is converted to monothiolate-complexed (5) and N-heterocyclic carbene-complexed (7) germanium(II) dithiolene complexes via Lewis base ligand exchange. A bis-dithiolene-based germylene (8), involving a 3c-4e S-Ge-S bond, has also been synthesized through controlled hydrolysis of 7. The bonding nature of 3, 5, and 8 was investigated by both experimental and theoretical methods. The chemistry at the germylene and dithiolene interface has rarely been explored. Here, we report a series of Lewis base-coordinated germanium(II) dithiolene complexes. Controlled hydrolysis of the carbene-coordinated germanium(II) dithiolene complex affords a dianionic bis-dithiolene-based germanium(II) species.image
