With the synthesis of bis[N,N´-diisopropylbenzamidinato(-)]silicon(II) [PhC(NiPr)2SiN(iPr)C(Ph)=NiPr], the prototype of a new class of silicon(II) compounds with one bidentate and one monodentate amidinato ligand has been made available in preliminary studies. With the additional imino functionality of the monodentate ligand, this donor-stabilized silylene can formally react as a tetracoordinate silicon(II) compound and thereby offers quite new perspectives for both silicon(II) and silicon(IV) chemistry [e.g. transformations of the type lambda3Si(II) -> lambda5Si(IV) and lambda3Si(II) -> lambda6Si(IV)]. In this project further silicon(II) compounds of this type will be synthesized and the reactivity profile of this new class of compounds will be studied systematically. Analogous donor-stabilized silylenes with guanidinato ligands will be included in these studies.

通过合成双[N，N ′-二异丙基苯甲脒基（-）]硅（II）[PhC（NiPr）2SiN（iPr）C（Ph）=NiPr]，初步研究了一类含有一个双齿和一个单齿脒基配体的新型硅（II）化合物的原型。在单齿配体的额外亚氨基官能团的情况下，这种供体稳定的亚甲硅烷基可以作为四配位硅（II）化合物形式上反应，从而为硅（II）和硅（IV）化学提供了相当新的前景[例如，类型的转化为3Si（II）-> 5Si（IV）和3Si（II）-> 6Si（IV）]。在该项目中，将进一步合成这种类型的硅（II）化合物，并将系统地研究这类新化合物的反应特性。类似的供体稳定的亚甲硅烷基与胍基配体将包括在这些研究中。
