1,1′-Diacetylferrocenebis(5-phenyl-1,3-oxazol-2-ylcarbonyl)hydrazone and its complexes

A new heterocyclic ferrocene derivative, 1,1′-diacetylferrocenebis(5-phenyl-1,3-oxazol-2-ylcarbonyl)hydrazone (H2Dfoh) and its coordination complexes, [M2(Dfoh)¡¤(OAc)2]¡¤nH2O [(M = Cu(II), Ni(II), Co(II), Cd(II), Pb(II), Mn(II)], were prepared by reacting H2Dfoh with the metal acetates and were characterized by elemental analyses, molar conductivities, IR, 1H NMR, UV spectra and thermal analyses. H2Dfoh appears to act as a bidentate ligand, coordinating to two metal atoms through the azomethine nitrogen and enolic oxygen atoms. OAc- coordinates to the metals as a symmetric bidentate ligand.

Irreversible inhibitors are therefore the equivalent of poisons in heterogeneous catalysis. Safety of 1,1′-Dibromoferrocene, Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction by binding to a specific portion of an enzyme and thus slowing or preventing a reaction from occurring. In a patent£¬Which mentioned a new discovery about 1293-65-8

Selective borane reduction of phosphinoferrocene carbaldehydes to phosphinoalcohol-borane adducts. the coordination behaviour of 1-(diphenylphosphino)- 1?-(methoxymethyl)ferrocene, a new ferrocene O,P-hybrid donor prepared from such an adduct

The reduction of ferrocene phosphino-aldehydes, R2PfcCHO (R = Ph, 2; Cy, 3; fc = ferrocene-1,1?-diyl, Cy = cyclohexyl) and (S p)-[Fe(eta5-C5H3-1-CHO-2-PPh 2)(eta5-C5H5)] ((S p)-4), with BH3¡¤THF or BH3¡¤ SMe2 in THF at 0 C selectively afforded the corresponding phosphinoalcohol-borane adducts, R2PfcCH2OH¡¤BH 3 (R = Ph, 5; Cy, 6) and (Sp)-[Fe(eta5-C 5H3-1-CH2OH-2-PPh2) (eta5-C5H5)]¡¤BH3 ((S p)-7), in quantitative yields. In contrast, the reactions performed at elevated temperatures favoured the formation of methyl derivatives (e.g., Ph2PfcCH3¡¤BH3 (8)) resulting from overreduction (deoxygenation). The crystal structures of 3, 5, (S p)-7, 8 and Cy2PfcBr (9) have been determined by single-crystal X-ray diffraction analysis. The crystal assemblies of adducts 5 and (Sp)-7 are built up by means of C-H…O contacts, O-H…HB dihydrogen bonds and other soft interactions but, surprisingly, not via the conventional O-H…O hydrogen bonds. Adduct 5 was smoothly deprotected to give the corresponding free phosphine, Ph2PfcCH 2OH (1), and was further used for the preparation of a hybrid phosphinoether ligand, Ph2PfcCH2OMe (11). The latter compound was studied as a donor for Group 8-10 metal ions and for Cu(i), whereupon the following complexes were isolated and structurally characterised: [(eta6-p-cymene)RuCl2(11-kappaP)] (12*), [(eta6-p-cymene)RuCl(11-kappaP)(MeCN)][SbF6] (13*), [RhCl(cod)(11-kappaP)] (cod = eta2: eta2-cycloocta-1,5-diene; 14), trans-[PdCl2(11-kappaP) 2] (trans-15*), [PdCl(mu-Cl)(11-kappaP)]2 (16*), cis- and trans-[PtCl2(11-kappaP)2] (cis-17 and trans-17*), and [Cu(CF3SO3-kappaO)(11- kappaP)(H2O)] (18) (the asterisk indicates that the crystal structure was determined). In all these compounds, ligand 11 behaves as a P-monodentate donor while its ether group remains uncoordinated. This probably reflects structural flexibility of 11 resulting from the presence of the methylene linker and also distinguishes 11 from its known, non-spaced analogue Ph2PfcOMe.

Study of the protection performance of self-assembled monolayers on copper with the scanning electrochemical microscope

The protection performance of self-assembled monolayers (SAMs) formed by 2-(Pyridin-2-yliminomethyl)-phenol (HL) on the surface of copper has been studied in situ with the scanning electrochemical microscope (SECM). The pitting dynamic processes were observed in sodium chloride solution without the presence of SAMs, but they tended to be inhibited by SAMs if the assembly time was long enough. During the scanning process, the self-assembled method decreases the interaction between the HL molecules and the SECM tip greatly.

Micro ring-disk electrode probes for scanning electrochemical microscopy

The construction and characterisation of ring-disk (RD) microelectrodes suitable for use in scanning electrochemical microscopy (SECM) is reported. Such RD electrodes are proposed as probes for novel generator-collector SECM experiments. In this case, the interaction of both the reactants and products with the substrate under investigation can be followed simultaneously from a single approach curve to the substrate. Examples of such approach curves to conducting and insulating substrates are given to demonstrate the potential of this new mode of SECM operation.

Synthesis and characterization of ferrocenylalcohol derivatives of hexachlorocyclotriphosphazene. X-ray crystal structure of N3P3Cl5OCH2CH2C5H4FeCp

The preparation of 1-ferrocenyl-2-propanol (5) from lithioferrocene and propylene oxide is described. The reaction of lithium diisopropylamide with 2-ferrocenylethanol (3) or 1-ferrocenyl-2-propanol (5), followed by the addition to hexachlorocyclotriphosphazane (1) provides N3P3Cl6-n (OCHRCH2C5H4FeCp)n [R=H, n=1 (3) or 2 (4); R=CH3, n=1 (6)]. The corresponding reactions with ferrocenylmethanol lead to degradation products via a phosphazene-phosphazene rearrangement. The substitution pattern observed for N3P3C14(OCH2CH2C5H4FeCp)2 (4) suggests that the reaction follows a predominantly cis-non-geminal pathway. The substituted phosphazene derivatives were characterized by standard means including 31P-NMR, mass spectrometry, elemental analysis and cyclic voltammetry. An X-ray crystal structure of N3P3C15(OCH2CH2C5H4FeCp) (3) was obtained.

Comparing the reactivity of isomeric phosphinoferrocene nitrile and isocyanide in Pd(ii) complexes: synthesis of simple coordination compounds vs. preparation of P-chelated insertion products and Fischer-type carbenes

Isomeric phosphinoferrocene ligands, viz. 1?-(diphenylphosphino)-1-cyanoferrocene (1) and 1?-(diphenylphosphino)-1-isocyanoferrocene (2), show markedly different coordination behaviours. For instance, the reactions of 1 with [PdCl2(MeCN)2] and [(LNC)Pd(mu-Cl)]2 (LNC = [2-(dimethylamino-kappaN)methyl]phenyl-kappaC1) produced the ?phosphine? complexes [PdCl2(1-kappaP)2] (7) and [(LNC)PdCl(1-kappaP)] (8), and the latter was converted into the coordination polymer [(LNC)Pd(mu(P,N)-1)][SbF6] (9). Conversely, the reaction of 2 with [(LNC)Pd(mu-Cl)]2 involved coordination of the phosphine moiety and simultaneous insertion of the isocyanide group into the Pd-C bond, giving rise to the P,eta1-imidoyl complex [PdCl(Ph2PfcN?CC6H4CH2NMe2-kappa3C,N,P)] (10; fc = ferrocene-1,1?-diyl). Compound 10 was further transformed into the Fischer carbene [PdCl(Ph2PfcN(Me)CC6H4CH2NMe2-kappa3P,C,N)][BF4] (11) by methylation with [Me3O][BF4]. The reactions of 2 with Pd-Me and Pd(eta3-allyl) precursors also led to imidoyl complexes [Pd(mu-Cl)(Ph2PfcN?CR-kappa2C,P)]2 (R = Me: 12, R = allyl: 15), which were cleaved with PPh3 into the corresponding monopalladium complexes [PdCl(PPh3)(Ph2PfcN?CR-kappa2C,P)] (R = Me: 13, R = allyl: 16). The treatment of 12 and 15 with thallium(i) acetylacetonate (acac) produced [Pd(acac-O,O?)(Ph2PfcN?CR-kappa2C,P)] (R = Me: 17, R = allyl: 18). Through proton transfer, these complexes reacted with Ph2PCH2CO2H, ultimately producing bis-chelate complexes [Pd(Ph2PCH2CO2-kappa2O,P)(Ph2PfcN?CR)] (R = Me: 19, R = prop-1-enyl (sic!): 20). In addition, compound 13 was converted into the P-chelated carbene [PdCl(PPh3)(Ph2PfcN(Me)CMe-kappa2C,P)][BF4] (14). Compounds 10, 11, 13 and 14 were studied by cyclic voltammetry and by DFT computations.
