Mono and difunctionalisation of chiral ferrocenyl bis-acetals. X-Ray crystal structure of bis-1,1?-[(2S, 4S)-(hydroxymethyl)-2-dioxane1,3]-ferrocene

The chiral 1,1?-bis-acetals, bis-1,1?-[(2S, 4S)-(hydroxymethyl)-2-dioxane1,3]-ferrocene (3) and 1,1?-bis-1,1?-[(2S, 4S)-(methoxymethyl)-2-dioxane1,3]-ferrocene (4) were synthesized. (3) was crystallographically characterised. The ortholithiation of (4) was studied in various conditions. Fair yields of monosubstituted compounds could be obtained with a complete regioselectivity in favor of the 2 position but the diastereoselectivities were moderate (up to 35%). Some disubstituted compounds can be isolated but in low yields (up to 8%). The regioselectivity is complete in favor of the 2,2?-disubstituted isomer. Only the diastereoisomer with two opposite planar chiralities is observed.

The synthesis and properties of bis-1,1?-(porphyrinyl)ferrocenes

Ferrocene-bridged bisporphyrins have been synthesized by the condensation of corresponding dipyrromethane-derived diols with a bisdipyrromethane. Purification of the final compounds has been achieved without chromatography. The specific geometry of these bisporphyrins makes them valuable starting points for building complex molecular and supramolecular structures. In particular it provides a core to which multiple sites of attractive intermolecular interactions can be attached thereby creating compounds predisposed to form complex networks by association. We have studied the structure of bis-1,1?-(porphyrinyl)ferrocenes by 1H NMR, UV-Vis and electrochemistry. Results have shown that complex dynamic processes occur in these molecules (which may involve conformers, formation of H-aggregates and tautomers) and that they have non-typical electrochemical behaviour.

Synthesis and hydrolysis of [alkenyl(alkoxy)carbene]manganese complexes: Evidence for a transient allylic intermediate on the way to alpha,beta-unsaturated aldehydes

A variety of alkenylcarbene complexes [Cp'(CO)2Mn= C(OEt)CH=CHR] (3) (Cp’ = TiS-MeCsH4) was obtained in a straightforward manner upon aldol condensation of [Cp'(CO)2Mn=C(OEt)CH3] (1) with aromatic and alpha,beta- unsaturated aldehydes RC(H)O (2). The reaction is totally stereoselective, giving (E)- or (all-E)-alkenylcarbenes only. The protonation of 3 at low temperature followed by reaction with water affords the alpha,beta-unsaturated aldehyde complexes [Cp'(CO)2Mn(n2-RCH=CHCHO] (5), from which the aldehydes RC(H)=C(H)C(H)O (6) were displaced by acetonitrile. The intermediate aldehyde complexes are shown to result from the hydrolysis of a transient cationic pi- allyl species [Cp'(CO)2Mn(n3-RCHCHC(OEt)H]+ ([4]+) formed upon protonation of 3.

Synthesis and characterisation of the new diaza ferrocene macrocycle 1,1?-( 2,6-diazahepta-1,6-diene) ferrocene and its parent amine 1,1?-( 2,6-diazaheptane ) ferrocene

Reaction of ferrocene-1,1?-dicarbaldehy de and propylenediamine yields the Schiff-base derivative 1,1?-(2,6-diazahepta-1,6-diene)-ferrocene (1). The molecular structure of 1 has been determined by single crystal X-ray analysis. It crystallises in the monoclinic system, space group P21/c, a=13.507(3), b=9.800(2), c=10.086(2) A, beta=110.81(3), Z=4 and V=1248.0(5) A3. Refinement of the atomic parameters by least-squares techniques gave a final R factor of 0.074 for 1588 observed reflections having 1>2sigma(1), Hydrogenation of 1 with LiA1H4 results in the parent amine 1,1?-(2,6-diazaheptane)ferrocene (2). The protonation of 2 has been investigated by potentiometry in water in the pH range 11-6. At pH lower than 6, 2 is unstable in solution. The E1/2 potential for 2 is pH-dependent (E1/2(pH 11) = 255, E1/2(pH 6) =435 mV). A similar behaviour was also observed in THF:water (60:40 vol./vol.). The electrochemical behaviour for 1 and 2 has also been studied in CH2Cl2.

Ferrocene substituted nitronyl nitroxide and imino nitroxide radicals. Synthesis, X-ray structure and magnetic properties

The synthesis, X-ray structure and magnetic properties of two new ferrocene substituted nitroxide monoradicals are described. The magnetic susceptibility data was nicely fitted in both cases to the Curie-Weiss law yielding the Weiss constants of theta=-1.8 and -1.1 K for radicals 1 and 2, respectively. This result evidenced the presence of very weak antiferromagnetic intermolecular interactions between neighbor molecules. Moreover, the X-ray structure of the key precursor 2,3-bis(hydroxyamino-)-2,3-dimethylbutane (3) is also included.

Some insights into the gold-catalysed A3-coupling reaction

A series of cyclometallated and functionalised NHC gold(I) and gold(III) complexes, many of which feature chiral ligands, and their application to A3-coupling reactions is presented. Gold(III) complexes were found to be particularly effective catalysts for the coupling in a range of solvents, however no asymmetric induction was obtained when using chiral gold complexes and the rate of product formation was found to be similar even when using different ligand systems. In-situ NMR analysis of these reactions indicates that decomposition of the catalyst occurs during the course of the reaction while TEM studies revealed the presence of gold nanoparticles in crude reaction mixtures. Taken together these data suggest that the gold nanoparticles, rather than the intact gold complexes, could be the catalytically active species, and if so this may have significant implications for other gold-catalysed systems.

Synthesis, characterization and third-order nonlinear optical properties of symmetrical ferrocenyl Schiff base materials

Six symmetrical ferrocenyl Schiff base materials were synthesized and characterized by UV, 1H NMR, mass spectrometry (MS) and elemental analysis. Their off-resonant third-order nonlinear optical properties were measured using femtosecond laser and degenerate four-wave mixing (DFWM) technique. The third-order nonlinear optical susceptibilities chi(3) were 1.961-6.363 ¡Á 10-13 esu. The nonlinear refractive indexes n2 were 3.609-11.716 ¡Á 10-12 esu. The second-order hyperpolarizabilities gamma of these molecules were 1.967-6.388 ¡Á 10-31 esu. The response time were 45.759-73.079 fs.
