The synthesis of two N-aryl substituted 2-silaimidazolidenes 9a, b by metal-reduction of the appropriate silicon(IV) heterocycles is reported. Structural as well as spectroscopic data obtained for the N-aryl substituted N-heterocyclic silylenes (NHSi) are very close to those obtained previously for their N-alkyl substituted counterparts. NHSis 9a, b are used as starting materials for the synthesis
据报道,通过适当的硅(IV)杂环的金属还原,合成了两个N-芳基取代的2-硅酰胺基氮杂环丁烷9a,b。由N-芳基取代的N-杂环亚甲硅烷基(NHSi)获得的结构和光谱数据与先前由其N-烷基取代的对应物获得的结构和光谱数据非常接近。NHSis图9a,b被用来作为起始原料的一系列dichalcogenadisiletanes的合成19 - 24和用于单亚甲硅基钨络合物的29。反应性研究表明,N-芳基取代的NHSis 9a,b与先前描述的N-烷基取代的亚甲硅烷基之间仅存在少许差异。
