A facile transesterification route to ferrocenyl esters

In the presence of tetrabutylammonium hydroxide as catalyst and at room temperature, ethyl ferrocenecarboxylate, ethyl ferrocenylacetate, ethyl 3-ferrocenylpropanoate, 1,1?-ferrocenyl-bis(ethyl propanoate), ethyl 3-ferrocenylpropenoate and 1,1?-ferrocenyl-bis(ethyl propenoate) undergoes facile transesterification reaction with aliphatic, benzyl and allyl alcohols to furnish the corresponding ferrocenyl esters in good to excellent yields. Ring closing metathesis of the ester Fc-1,1?-(CHCH-CO2CH 2CHCH2)2 yields the corresponding closed loop ferrocenyl ester.

Playing peekaboo with graphene oxide: A scanning electrochemical microscopy investigation

Scanning electrochemical microscopy (SECM) can image graphene oxide (GO) flakes on insulating and conducting substrates. The contrast between GO and the substrate is controlled by the electrostatic interactions that are established between the charges of the molecular redox mediator and the charges present in the sheet/substrate. SECM also allows quantitative measurement-at the nano/microscale-of the charge transfer kinetics between single monolayer sheets and agent molecules. This journal is

Synthesis of new ferrocene derivatives with a 4,5-dichloroisothiazole fragment

Conjugates of ferrocene and 4,5-dichloroisothiazole were synthesized, where the ferrocene and isothiazole moieties are linked through various structural fragments. The acylation of ferrocene with 4,5- dichloroisothiazole-3-carbonyl chloride gave (4,5-dichloroisothiazol-3-yl) ferrocenyl ketone; the acylation of aminomethylferrocene furnished the corresponding amide. The esterification of ferrocene-1,1?-dicarboxylic acid with 4,5-dichloroisothiazol-3-yl-methanol resulted in the formation of the corresponding ester. The condensation of 1,1?-diacetylferrocene with 4,5-dichloroisothiazole-3-carbaldehyde afforded ferrocenophane containing 4,5-dichloroisothiazole moieties.

Triad and cyclic diad compounds of [60]fullerene with metallocenes

Metallocene-bridged [60]fullerene triads and cyclised metallocene-[60] fullerene diads are formed via [3 + 2] cycloaddition reactions of [60]fullerene with metallocene dialdehyde and an amino acid. In the case of cyclic diads only one regioisomer is formed, as determined by UV-vis and NMR spectroscopic studies. These compounds have both electron donor (metallocene) and acceptor ([60]fullerene) components and give three electrochemically reversible one-electron reductions for each [60]fullerene moiety. For the ferrocene-containing compounds, an electrochemically reversible one-electron oxidation process is observed, with an irreversible oxidation observed for the ruthenocene analogues.

Synthesis of Two Isomeric Ferrocene Phosphanylcarboxylic Acids and their PdII Complexes with and without Auxiliary ortho-Metalated C,E-Ligands (E = N and S)

Two homologous ferrocene phosphanylcarboxylic acids, viz., 1?-[(diphenylphosphanyl)methyl]ferrocene-1-carboxylic acid (HL1) and [1?-(diphenylphosphanyl)ferrocenyl]acetic acid (HL2), were synthesized and studied as ligands in PdII complexes. The addition of these hybrid donors to [PdCl2(MeCN)2] led to the bis-phosphane complexes trans-[PdCl2(HL1-kappaP)2] and trans-[PdCl2(HL2-kappaP)2]. In contrast, the reactions of HL1 and HL2 with the PdII acetylacetonate (acac) complexes [(LYC)Pd(acac)], where LYC = 2-[(dimethylamino-kappaN)methyl]phenyl-kappaC1 (LNC) and 2-[(methylthio-kappaS)methyl]phenyl-kappaC1 (LSC), proceeded under proton transfer and replacement of the acac ligand, giving rise to O,P-bridged phosphanylcarboxylate dimers [LYCPd(mu(P,O)-L1)]2 and molecular chelates [LYCPd(L2-kappa2O,P)]2, respectively. The analogous reactions involving 1?-(diphenylphosphanyl)-1-ferrocenecarboxylic acid (Hdpf) provided the macrocyclic tetramer [LNCPd(mu(P,O)-dpf)]4 and the dimer [LSCPd(mu(P,O)-dpf)]2. The reactions of HL1 with [Pd(acac)2] only led to an ill-defined, insoluble material, whereas those with HL2 produced a separable mixture of the bis-chelate complexes trans-[Pd(L2-kappa2O,P)2], cis-[Pd(L2-kappa2O,P)2], and [Pd(acac)(L2-kappa2O,P)].

Preparation of metal mesoporphyrin halide compounds

A method of preparing metal mesoporphyrin halide compounds is described. The metal mesoporphyrin halide compound may be formed by forming a novel mesoporphyrin IX intermediate compound and then converting the mesoporphyrin IX intermediate to the metal mesoporphyrin halide through metal insertion. The novel intermediate compound may be formed by a catalytic hydrogenation of hemin in acid and subsequent recovery.

A class of novel, easily accessible and air-stable 1-[bis(trifluoromethyl) phosphine]-1′-oxazolinylferrocene ligands has been synthesized from ferrocene. It became apparent that these ligands can be used in the regio- and enantioselective Pd-catalyzed allylic alkylation of monosubstituted allyl substrates in a highly efficient manner. Excellent regio- and enantioselectivity could be obtained for a wide range of substrates.

Cyclometallation of ferrocenylimines III. Regioselectivity in Hg(II) cyclometallated complexes

The synthesis and mercuration of a series of Schiff bases 1?-benzoyl-1-[(arylimino)phenylmethyl]ferrocene (aryl: a variety of substituted phenyls) have been studied. In all cases the mercuration occurred at the 2-position of the ferrocene ring. Oxygen ? mercury coordinated products were not obtained. The X-ray crystal structure of [2-chloromercurio-1-[((phenylimino)phenylmethyl)-1?-benzoyl] ferrocene 5c has been determined; this crystallizes in the monoclinic, space group P21/c with a =10.168(3), b= 16.105(3), c = 15,463(4)A, beta = 103.61(2) and Z = 4. Refinement of atomic parameters gave an R factor of 0.038 (Romega = 0.055) for 2440 unique reflections having 1>3sigma(1). The structure confirms the formation of a five-membered metallocycle on the ferrocene moiety.
