Study on Transition Metal Complexes Coordinated with Low-ValentSilicon and Germanium

以二氯锗烯为起始原料，与阴离子金属配合物反应，合成了含低价锗配体的过渡金属配合物氯代锗烯。随后，照射的金属germylenes的溶液导致氯germylyne络合物的形成。通过这些反应的应用，由（氯锗基）氯锗烯合成了二锗-亚乙烯基配合物。此外，还合成了含N，O-双齿配体的锗烯钨配合物。在（氯锗烯）甲基钨配合物中发现了一种新的非对映选择性Cl/Me交换反应。

As a starting material of transition metal complexes containing low-valent germanium ligands, chlorometallogermylenes were synthesized by reaction of dichlorogermylenes with anionic metal complexes. Subsequently, irradiation of a solution of the metallogermylenes led to formation of chlorogermylyne complexes. By the application of these reactions, digermavinylidene complexes were synthesized from a (chlorogermyl)chlorogermylene. Moreover, tungsten complexes coordinated with germylenes having N,O-bidentate ligands were synthesized. A novel diastereoselective Cl/Me exchange reaction was found in the (chlorogermylene)methyltungsten complexes.
