[PhP(S)(NMeNH2)2]ZnCl2: A Reagent for the Synthesis of Polymetallic Complexes. X-ray Structure of the Electroactive Compound [PhP(S)(NMeN=CHC5H4FeCp)2]ZnCl2

The zinc complex [PhP(S)(NMeNH2)2]ZnCl2 (2), cleanly obtained by reaction of the phosphodihydrazide PhP(S)(NMeNH2)2 (1) with ZnCl2, is a good reagent in producing new polymetallic compounds by condensation reaction with aldehydes. The reaction of 2 with terephthalaldehyde (3) in a 2/1 or 1/1 stoichiometry leads selectively to the acyclic zinc compound [C6H4-1,4-(CH=NNMePhP(S)NMeNH2)2][ZnCl2]2 (6) or to the macrocyclic zinc complex [PhP(S)C6H4-1,4-(CH=NNMe)2]2[ZnCl2]2 (7). Reaction of compound 2 with 2 equiv of ferrocenecarbaldehyde affords the zinc-iron phosphodihydrazone complex [PhP(S)(NMeN=CHC5H4FeCp)2]ZnCl2 (8) whose structure has beendetermined by X-ray crystallography. Crystal data: triclinic P1-, with a = 12.798(1) A, b = 14.639(2) A, c = 11.744(2) A, alpha =111.74(1)¡ã, beta = 115.92(1)¡ã, gamma = 68.36(1)¡ã, V = 1780.9 A**3, Z = 2; R = 0.037, Rw = 0.044 for 3345 observations and 448 variable parameters. In this neutral trimetallic complex, the Zn(II) center adopts a pseudotetrahedral geometry. This structure is characterized by a five-membered ring with the Zn(II) bonded to the S atom and to one of the N atoms of the phosphodihydrazone ligand PhP(S)(NMeN=CHC5H4FeCp)2 (9). Variable-temperature NMR investigations of 8 show that 9 can act as a hemilabile ligand toward ZnCl2 through an exchange process between the two hydrazone arms in solution. Electrochemical study ofcomplex 8, when compared to the ferrocenyl ligand 9, shows that ZnCl2 complexation induces a shift of 80 mV toward a more anodic potential. Reaction of 2 with the ferrocene-1,1′-dicarbaldehyde also produces the bisferrocenyl dizinc macrocycle [Fe(C5H4CH=NNMePhP(S)NMeN=CHC5H4)2Fe][ZnCl2]2 (10).

Syntheses of chiral ferrocenophanes and their application to asymmetric catalysis

N-Substituted 2-aza-[3]-ferrocenophanes were easily synthesized from 1,1?-ferrocenedicarbaldehyde and aliphatic amines in high yields. One of the ferrocenophanes served as a ligand for the copper-catalyzed oxidative coupling of 2-naphthol derivatives to give the products in good yields with up to 92% ee, and it also efficiently catalyzed the asymmetric Michael addition reaction as an organocatalyst.

Bis [1,1?-N,N?-(2-picolyl)aminomethyl] ferrocene as a redox sensor for transition metal ions

The compound bis[1,1?-N,N?-(2-picolyl)aminomethyl]ferrocene, L1, was synthesized. The protonation constants of this ligand and the stability constants of its complexes with Ni2+, Cu2+, Zn2+, Cd2+ and Pb2+ were determined in aqueous solution by potentiometric methods at 25C and at ionic strength 0.10 mol dm-3 in KNO3. The compound L1 forms only 1:1 (M:L) complexes with Pb2+ and Cd2+ while with Ni 2+ and Cu2+ species of 2:1 ratio were also found. The complexing behaviour of L1 is regulated by the constraint imposed by the ferrocene in its backbone, leading to lower values of stability constants for complexes of the divalent first row transition metals when compared with related ligands. However, the differences in stability are smaller for the larger metal ions. The structure of the copper complex with L1 was determined by single-crystal X-ray diffraction and shows that a species of 2:2 ratio is formed. The two copper centres display distorted octahedral geometries and are linked through the two L’ bridges at a long distance of 8.781(10) A. The electrochemical behaviour of L1 was studied in the presence of Ni2+, Cu2+, Zn2+, Cd2+ and Pb2+, showing that upon complexation the ferrocene – ferrocenium half-wave potential shifts anodically in relation to that of the free ligand. The maximum electrochemical shift (DeltaE1/2) of 268 mV was found in the presence of Pb2+ followed by Cu2+ (218 mV), Ni 2+ (152 mV), Zn2- (111 mV) and Cd2+ (110 mV). Moreover, L1 is able to electrochemically and selectively sense Cu2+ in the presence of a large excess of the other transition metal cations studied.

Triggered Metal Ion Release and Oxidation: Ferrocene as a Mechanophore in Polymers

The introduction of mechanophores into polymers makes it possible to transduce mechanical forces into chemical reactions that can be used to impart functions such as self-healing, catalytic activity, and mechanochromic response. Here, an example of mechanically induced metal ion release from a polymer is reported. Ferrocene (Fc) was incorporated as an iron ion releasing mechanophore into poly(methyl acrylate)s (PMAs) and polyurethanes (PUs). Sonication triggered the preferential cleavage of the polymers at the Fc units over other bonds, as shown by a kinetic study of the molar mass distribution of the cleaved Fc-containing and Fc-free reference polymers. The released and oxidized iron ions can be detected with KSCN to generate the red-colored [Fe(SCN)n(H2O)6?n)](3?n)+ complex or reacted with K4[Fe(CN)6] to afford Prussian blue.

Poly(ferrocenylenevinylene) from ring-opening metathesis polymerization of ansa-(vinylene)ferrocene

The vinylene-bridged ansa-ferrocene complex [(eta5-C5H4)CH=CH(eta5-C 5H4)]Fe (1) was synthesized by the McMurry coupling of 1,1?-ferrocenedicarbaldehyde (2). The ring opening metathesis polymerization (ROMP) of this strained metallocene gave poly(ferrocenylenevinylene) (3) as an insoluble orange solid which has a conductivity of 10-3 Omega-1 cm-1 after doping with iodine. Partially soluble materials resulted when 1 was copolymerized with norbornene to yield a block copolymer.

Rigid ferrocenophane and its metal complexes with transition and alkaline-earth metal ions

The rigid [6]ferrocenophane, L1, was synthesised by condensation of 1,1?-ferrocene dicarbaldehyde with trans-1,2-diaminocyclohexane in high dilution at r.t. followed by reduction. When other experimental conditions were employed, the [6,6,6]ferrocenephane (L2) was also obtained. Both compounds were characterised by single crystal X-ray crystallography. The protonation of L1 and its metal complexation were evaluated by the effect on the electron-transfer process of the ferrocene (fc) unit of L1 using cyclic voltammetry (CV) and square wave voltammetry (SWV) in anhydrous CH3CN solution and in 0.1 M nBu4NPF6 as the supporting electrolyte. The electrochemical process of L1 between -300 and 900 mV is complicated by amine oxidation. On the other hand, an anodic shift from the fc/fc+ wave of L1 of 249, 225, 81 and 61 mV was observed by formation of Zn2+, Ni2+, Pd2+ and Cu2+ complexes, respectively. Whereas Mg2+ and Ca2+ only have with L1 weak interactions and they promote the acid-base equilibrium of L1. This reveals that L1 is an interesting molecular redox sensor for detection of Zn2+ and Ni2+, although the kinetics of the Zn2+ complex formation is much faster than that of the Ni2+ one. The X-ray crystal structure of [PdL1Cl2] was determined and showed a square-planar environment with Pd(II) and Fe(II) centres separated by 3.781(1) A. The experimental anodic shifts were elucidated by DFT calculations on the [ML1Cl2] series and they are related to the nature of the HOMO of these complexes and a four-electron, two-orbital interaction.

Polarization Mechanisms and Properties of Substituted Ferrocenes. A Comparative Study

The polarizability alpha, and second hyperpolarizability, gamma, of some ferrocene derivatives are determined by using an optimized semiempirical approach.The bonding in ferrocene has been investigated through the study of the above polarization properties.The results from the ferrocene derivatives have been correlated with the corresponding substituted benzenes.Scales have been presented, where the derivatives are classified according to their polarization properties.The effect of delocalized ? electrons, charge transfer, and geometry variations on alpha and gamma are commented upon.Selected results of various other properties (e.g., the first hyperpolarizability) are used to demonstrate that some mechanisms (e.g., charge transfer) and changes in geometry may have widely different effects on the molecular properties.Common trends and patterns of behavior are recognized and discussed.The reported results are in good agreement with the experimentally determined ones.

Optical Nonlinearities of Organometallic Structures: Aryl and Vinyl Derivatives of Ferrocene

With an objective to understand the nonlinear optical properties of organometallic structures, various aryl and vinyl derivatives of ferrocene were synthesized and their nonlinear optical properties were investigated by using degenerate four-wave mixing.The molecular second hyperpolarizability gamma increases strongly with the length of the conjugated ?-electron system.The results show that effective conjugation is determined predominantly by the length of the aryl-vinyl system; the contribution from the ferrocenyl group is less significant.The d-d resonance of the metal in the ferrocene unit does not appear to make an important contribution to optical nonlinearity.The experimental results on ferrocene are compared with those from a recent theoretical study using semiempirical calculations.Although a qualitative agreement with the theoretical result is found, the experimental value of gamma determined by our method is about 4 times larger.Possible sources of such discrepancies are discussed.
