There are three basic categories that ferrocene-containing dendrimers can be placed in: (a) dendrimers with ferrocene cores, (b) dendrimers with peripheral ferrocene groups, and (c) dendrimers with ferrocene at the core and the peripheral.〔Muller, C. et al., ''J. Organomet. Chem.'', 2000, 600, 127-143〕 ==Synthesis== Ferrocene-containing dendrimers can be synthesized by both convergent and divergent methods. Some of the first dendrimers of this type, were made by attaching ferrocene units to small silicon containing dendrimers.〔Hudson, R.D.A, ''J. Organomet. Chem.'', 637-639 (2001), 47-69〕 Dendrimers with peripheral ferrocene groups are usually synthesized by attaching ferrocene to the core by either olefin metathesis or by hydrosilylation reactions.〔 As an example, compound 1 was synthesized by a divergent approach in which tetraallylsilane undergoes Pt-catalyzed hydrosilylation to form the core. This core was then reacted with ferrocenyllithium to form 1.〔Alonso B. et al., ''Chem. Commun.'', 1994, 2575-2576〕 Convergent approaches can also be used to make dendrimers with peripheral ferrocene. As an example, figure 1 shows a 54-ferrocene dendrimer which was synthesized by a fast convergent approach.〔Nlate, S. et al., "Ferrocenylsilylation of Dendrons: A Fast Convergent Route to Redox-Stable Ferrocene Dendrimers", ''Chem. Commun.'', 2000, 417-418〕 Dendrimers with ferrocene cores can be synthesized by first making ferrocene derivatives with functional groups. An example of this would be compounds 2 and 3. These compounds can undergo hydrosilylation reactions to form dendrimers. As an example, decaallylferrocene (3) can undergo hydrosilylation with dimethylferrocenylsilane to form a decaferrocenyl functionalized ferrocene as is shown in figure 2.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ferrocene-containing dendrimers」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
