Synthesis, photophysical and electrochemical properties of 1,2,3-triazolyl bridged ferrocenyl dendrimers through click chemistry

Triazole-based novel dendrimers with ferrocenyl surface groups have been achieved through click chemistry, both by divergent and convergent approaches.

Synthesis and metallation of ferrocenylimines derived from ligating diaminoheteroarenes

A regioisomeric mixture of 1,1?-didodecylferrocenedicarbaldehydes 3 was prepared from the reaction of a regioisomeric mixture of 1,1?-didodecyldilithioferrocenes and dimethylformamide. Three ligating heteroaromatics were synthesized each containing two amino substituents: 5,5?-diamino-2,2?-bipyridine and 5,5?-diamino-2,2? : 6?,2?-terpyridine were prepared from appropriate dinitro compounds by reduction with palladium on charcoal-hydrazine hydrate. The reaction of 2-cyano-5-nitropyridine and hydrazine hydrate gave an isolable amidine derivative and this was transformed with hydrazine in a separate reaction under more forcing conditions into 3,6-bis(5-amino-2-pyridyl)-1,2-dihydro-1,2,4,5-tetrazine. The latter was converted into the tetrazine by oxidation (2,3-dichlpro-5,6-dicyano-1,4-benzoquinone) and then trifluoroacetylated [(CF3CO)2O] to give the bis(trifluoroacetylamino) derivative. Diels-Alder reaction of the latter with dodec-1-yne afforded 4-n-decyl-3,6-bis[5-(trifluoroacetylamino)-2-pyridyl]pyridazine which was deprotected (K2CO3) to give the corresponding diamine. Bis(ferrocenyl) Schiff bases were prepared from ferrocenecarbaldehyde and the appropriate diamine in either uncatalysed or acid-catalysed condensations. Tetracarbonylmolybdenum complexes were prepared by treating the appropriate diamines with molybdenum hexacarbonyl. Reaction of one of these complexes with ferrocenecarbaldehyde gave a heterobimetallic complex.

Crosslinking catalysis-active center of hemin on the protein scaffold toward peroxidase mimic with powerful catalysis

An enzyme mimic synthesis protocol has been proposed by simply cross-linking the redox active center of peroxidase onto a protein scaffold. Colorimetric assays and kinetic studies indicate that the developed peroxidase mimic can present much stronger catalysis and better aqueous stability than native hemin.

Additive-manufactured (3D-printed) electrochemical sensors: A critical review

Additive manufacturing or three-dimensional (3D)-printing is an emerging technology that has been applied in the development of novel materials and devices for a wide range of applications, including Electrochemistry and Analytical Chemistry areas. This review article focuses on the contributions of 3D-printing technology to the development of electrochemical sensors and complete electrochemical sensing devices. Due to the recent contributions of 3D-printing within this scenario, the aim of this review is to present a guide for new users of 3D-printing technology considering the required features for improved electrochemical sensing using 3D-printed sensors. At the same time, this is a comprehensive review that includes most 3D-printed electrochemical sensors and devices already reported using selective laser melting (SLM) and fused deposition modeling (FDM) 3D-printers. The latter is the most affordable 3D-printing technique and for this reason has been more often applied for the fabrication of electrochemical sensors, also due to commercially-available conductive and non-conductive filaments. Special attention is given to critically discuss the need for the surface treatment of FDM 3D-printed platforms to improve their electrochemical performance. The insertion of biochemical and chemical catalysts on the 3D-printed surfaces are highlighted as well as novel strategies to fabricate filaments containing chemical modifiers within the polymeric matrix. Some examples of complete electrochemical sensing systems obtained by 3D-printing have successfully demonstrated the enormous potential to develop portable devices for on-site applications. The freedom of design enabled by 3D-printing opens many possibilities of forthcoming investigations in the area of analytical electrochemistry.

Transition metal cation and phosphate anion electrochemical recognition in water by new polyaza ferrocene macrocyclic ligands

New polyaza ferrocene macrocyclic ligands 4-7 have been synthesised and with 4, copper(II) and nickel(II) transition metal complexes isolated. Electrochemical investigations reveal these redox-active ligands can electrochemically sense various transition metal cations in polar organic solvents and in water at high pH values with ligands 4 and 5. Aqueous electrochemical competition experiments with Ni2+, Cu2+ and Zn2+ suggest 4 and 5 exhibit a selectivity preference for the copper(II) cation. At lower pH values (6-8) the respective protonated polyammonium forms of 4, 5 and 7 complex and electrochemically detect the biologically important phosphate anions, ATP and hydrogen phosphate in the aqueous environment.

N -Heterocyclic Carbene-Catalyzed Olefination of Aldehydes with Vinyliodonium Salts to Generate alpha,beta-Unsaturated Ketones

An organocatalyzed metal-free, direct olefination of aldehydes with vinyliodonium salts has been achieved by an N-heterocyclic carbene-promoted C-H bond activation. The reaction proceeds under very mild conditions, delivering a range of (hetero)aryl-vinyl ketones in good yields. The retention of the double bond configuration is uniformly observed, and the application of 2-methoxyphenyl auxiliary group in iodonium salts secures a complete selectivity of the vinyl transfer.

Scanning electrochemical microscopy: Surface interrogation of adsorbed hydrogen and the open circuit catalytic decomposition of formic acid at platinum

The surface interrogation mode of scanning electrochemical microscopy (SECM) is extended to the in situ quantification of adsorbed hydrogen, H ads, at polycrystalline platinum. The methodology consists of the production, at an interrogator electrode, of an oxidized species that is able to react with Hads on the Pt surface and report the amounts of this adsorbate through the SECM feedback response. The technique is validated by comparison to the electrochemical underpotential deposition (UPD) of hydrogen on Pt. We include an evaluation of electrochemical mediators for their use as oxidizing reporters for adsorbed species at platinum; a notable finding is the ability of tetramethyl-p-phenylenediamine (TMPD) to oxidize (interrogate) H ads on Pt at low pH (0.5 M H2SO4 or 1 M HClO4) and with minimal background effects. As a case study, the decomposition of formic acid (HCOOH) in acidic media at open circuit on Pt was investigated. Our results suggest that formic acid decomposes at the surface of unbiased Pt through a dehydrogenation route to yield Hads at the Pt surface. The amount of Hads depended on the open circuit potential (OCP) of the Pt electrode at the time of interrogation; at a fixed concentration of HCOOH, a more negative OCP yielded larger amounts of Hads until reaching a coulomb limiting coverage close to 1 UPD monolayer of H ads. The introduction of oxygen into the cell shifted the OCP to more positive potentials and reduced the quantified Hads; furthermore, the system was shown to be chemically reversible, as several interrogations could be run consecutively and reproducibly regardless of the path taken to reach a given OCP.

The use of a variety of different acylating agents in our studies demonstrates the scope of this reaction performed in these ionic liquid systems.

Asymmetric synthesis of planar chiral 2-mono- and 2,2?-disubstituted 1,1?-bisbenzoylferrocenes

An efficient and flexible asymmetric synthesis of planar chiral 2-mono- and 2,2?-disubstituted 1,1?-bisbenzoylferrocenes 4 and 6 is reported. Key step is a highly diastereoselective ortho-metalation of 1,1?-bisbenzoylferrocene 1 via the corresponding bis-SAMP-hydrazone 2 (de?96%), followed by trapping with various carbon, silicon, phosphorus and sulfur electrophiles. Cleavage of the monosubstituted hydrazones 3 led to monosubstituted ketones 4 (ee?98%). Further ortho-substitution of the hydrazones 3 afforded 2,2?-disubstituted hydrazones 5, which could be cleaved to disubstituted ferrocenyl diketones 6 (ee?99%). The new methodology allows a broad and flexible fine-tuning of ferrocenyl ligands desired in asymmetric catalysis. Ozonolysis or reductive hydrazone cleavage using TiCl3 or SnCl2 were the methods of choice to remove the auxiliary.
