在THF/TMEDA中,咪唑基二硫醚(2)与GeCl2•二恶烷(2)进行1:2反应,得到TMEDA -络合的二硫烯基germylene。化合物3通过路易斯碱配体交换转化为单硫酸盐配合物(5)和N杂环碳化合物配合物(7)锗(II)二硫烯配合物。以双-二硫代烯为基础的germylene(8),包含一个3c-4e S - Ge - S键,也通过7的可控水解合成。用实验和理论方法研究了3、5和8的成键性质。
The 1 : 2 reaction of the imidazole‐based dithiolate (2) with GeCl2• dioxane in THF/TMEDA gives3, a TMEDA‐complexed dithiolene‐based germylene. Compound3is 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 of7. The bonding nature of3,5, and8was investigated by both experimental and theoretical methods.
