Several new bridged trinuclear complexes of the general formula RSi[η5-C5H4M(CO)nR1]3, have been prepared in good yield from the reaction of the lithiated compounds (η5-C5H4Li)M(CO)nR1 (M = Mn, W, Fe; R1 = Me, Et, and benzyl) with various alkyl trichlorosilanes. The crystal and mlecular structure of MeSi[η5-C5H4Fe(CO)2C2H5]3 is presented. In addition, some limitations of the direct cyclopentadienyl
通式为RSi [η的几个新的桥接三核络合物5 -C 5 H ^ 4 M(CO)ñ - [R 1 ] 3,都以良好的收率制备从锂化化合物的反应(η 5 -C 5 H ^ 4栗)M(CO)n R 1(M = Mn,W,Fe; R 1 = Me,Et和苄基)与各种烷基三氯硅烷。晶体和MESI [η的mlecular结构5 -C 5 H ^ 4的Fe(CO)2 C ^ 2 ^ h 5 ] 3被表达。另外,讨论了直接环戊二烯基环金属化的一些限制。

of an unsaturated silicon cluster (siliconoid) with a polyhedral silsequioxane cage. Two derivatives with variable linker size are obtained by the corner-capping reaction of Ph7T7(ONa)3 with a trichlorosilane featuring a remote benzylic chloride functionality and the subsequent nucleophilic substitution of the latter by the anionic hexasilabenzpolarene-type Si6 siliconoid. Based on the recently proposed
通过不饱和硅簇(siliconoid)与多面体倍半硅氧烷笼的互连,合成了一种新的一氧化硅(SiO)势模型系统。通过 Ph 7 T 7 (ONa) 3与具有远程苄基氯化物官能团的三氯硅烷的封角反应以及随后用阴离子六硅苯并极化烯型 Si 6硅化物对后者进行亲核取代,获得了两种具有可变接头尺寸的衍生物。基于最近提出的 SiO 结构的异质簇模型,硅和氧之间的化学计量以 14:12 的 Si:O 比率重申了纳米复合材料的低氧化界面。
