Iron chains: The highly soluble, ferrocene-containing polymer [-fc-B(Mes)-]n (fc = Fe(C5H4)2, Mes = mesityl), with an average chain length of about 16 repeat units (n = 16), is readily accessible by a novel polycondensation reaction starting from fc(BBr2)2 and HSiEt3 (see scheme). The polymer contains three-coordinate boron centers, which are well-suited for the promotion of electron delocalization along the polymer chain. (Chemical Equation Presented).

    ABSTRACT: This textbook is intended to give an understanding of the basic principles that constitute the field of non-conventional polymers containing inorganic and organometalic units as the repeating units. Each chapter will be self-explanatory with a good background so that it can be easily understood at the senior undergraduate level. The principles involved in the preparation of these polymers, their characterisation and their applications will be discussed. Basic inorganic chemistry required for the understanding of each topic is presented so that the content of the chapter is readily understood.

    ABSTRACT: The trinuclear ferrocenophane [{Fe(eta(5)-C(5)H(4))(3)}(2)Ga(2)] (3) featuring two sp(2)-hybridized gallium atoms in bridging positions between three ferrocene-1,1'-diyl units represents a novel type of ferrocene derivative. Compound 3 is obtained by thermal treatment of 1,1'-bis(dimethylgallyl)ferrocene (1) in nondonor solvents or in diethyl ether as solvent and subsequent thermal decomplexation. The [1.1]ferrocenophane [{Fe(eta(5)-C(5)H(4))(2)}(2){GaMe}(2)] (2) is an intermediate in the formation of 3. The reaction of 3 with an excess of trimethylgallium leads back to 1 and proves the reversibility of the multistep reaction sequence. Theoretical calculations reveal a carousel-type D(3h) structure for 3. The compound can best be described as being composed of three only weakly interacting ferrocenediyl units covalently connected by gallium atoms without any pi-bond contribution in the Ga--C bonds. Owing to steric constraints 3 cannot be reduced to the dianion 3(2-), which would feature a Ga--Ga bond. Compound 3 represents a stereochemically rigid difunctional Lewis acid allowing the formation of the adducts 3 a-3 d possessing linear donor-aceptor-aceptor-donor arrangements. Crystal structure data for 3 a-3 d show a symmetry-reduced chiral ferrocenophane core (D(3h)-->D(3)). A polymeric rodlike structure is observed for 3 b and 3 d caused by pi-stacking effects (3 b) or by a difunctional donor-acceptor interaction (3 d). In solution, the chirality of the adducts is lost by rapid interconversion of the enantiomers. A cyclic voltammogram of 3 b in pyridine reveals three quasi-reversible oxidation steps at -356, -154, and 8 mV, indicating only weak electron delocalization in the cationic species. The redox potentials of the pyridine adduct 3 b are compared with those of other pyridine-stabilized gallyl-sustituted ferrocene derivatives and with ferrocene itself.

    ABSTRACT: 1,n′-Disubstituted ferrocenes with ketone/phthalimido (2) and ketone/amine substituents (3) were synthesised and characterised by IR, 1H NMR, 13C NMR, VT 1H NMR, UV/Vis spectroscopy, mass spectrometry and cyclic voltammetry. The molecular structure of 2 was confirmed by X-ray crystal structure determination. The dynamic behaviour was experimentally studied in solution and theoretically by DFT calculations. The thermal stability of the ketone/amine derivative 3 was investigated using thermal analyses.
