oxidation/reduction. In state I, the arm is attached via Cu+ complexation to a stericallyencumbered phenanthroline and in state II to a zinc porphyrin station. Toggling is realised by charging and discharging an external input signal, the ferrocene-appended diimine ligand 2. Addition of 2 leads to formation of the intermolecular complex [Cu(1)(2)]+ paralleled by a move of the py–pym arm to the zinc
A catalytically active three-component nanorotor is reversibly self-assembled and disassembled by remotecontrol. When zinc(II) ions (2 equiv.) are added as an external chemical trigger to the mixture of transmitter [Cu(1)]+ and pre-rotor assembly [(S)·(R)], two equiv. of copper(I) ions translocate from [Cu(1)]+ to the two phenanthroline sites of [(S)·(R)]. As a result, [Zn(1)]2+ forms along with the

Abstract A simple and convenient approach to the synthesis of the derivatives of unsymmetrical 1,1′-disubstituted cyclopropane-containing azinylferrocenes was suggested. A regioselective method for the Friedel—Crafts acylation of monoazinyl-substituted ferrocenes with a 4-chlorobutyryl chloride—AlCl3 mixture in CH2Cl2 under an inert atmosphere was elaborated. The acylation product on treatment with
摘要 提出了一种简单方便的合成不对称1,1'-二取代环丙烷含吖嗪基二茂铁衍生物的方法。详细阐述了在惰性气氛下,在CH 2 Cl 2中,用4-氯丁酰氯-AlCl 3混合物对单嗪基取代的二茂铁进行弗里德尔-克来福特酰化反应的区域选择性方法。在 DMSO 中用 Bu t OK处理的酰化产物很容易发生 HCl 的 γ-消除反应,得到相应的环丙烷。合成的化合物的结构通过红外光谱、1H和13C光谱、质谱和X射线衍射分析进行了确认。

The Friedel-Crafts acetylation (Ac2O/AlCl3) reaction of azinylferrocenes occurs regioselectively at position 1'. Acetylated derivatives upon reaction with Ph3P=CH2 give the corresponding 1-azinyl-1'-isopropenylferrocenes.
