1,2,3-triazole ferrocenyldendrimers through click chemistry approach and their optical and electrochemical properties

Novel ferrocenyl dendrimers with ferrocene as a surface group and with triazole as a bridging unit have been synthesised through click chemistry. The increasing numbers of triazole and ferrocenyl units at the antenna increase the light absorbing ability. The electrochemical behaviour changes with increasing ferrocenyl and triazole units.

Synthesis of controlled pi-extended conjugate nanostructures of 1,1?-ferrocene

Synthesis of the (E,E)-1,1?-ferrocene nanostructures having controlled pi-extended conjugation was satisfactory carried out starting of 1?-[2-(1,3-dioxolan)]-1-formylferrocene (1). The molecular unit (E)-1?-[2-(1,3-dioxolan)]-1-[beta-(p-iodophenyl)ethenyl]ferrocene (2), was obtained in excellent yield by treatment of 1 with p-iodobenzyl triphenylphosphonium ylid followed by Z?E isomerization, catalyzed by iodine, in quantitative yield. Compound (E)-2 was transformed in (E)-1?-{2-(1,3-dioxolan)-1-[beta-[4-(3-hydroxy-3-methyl-but-1-ynyl)-phenyl]-ethenyl}ferrocene, (E)-4, by palladium catalyzed cross-coupling with 2-methyl-but-3-yn-2-ol. (E)-4 gives (E)-1-[beta-(4-ethynylphenyl)-ethenyl]-1?-[2-(1,3-dioxolan)]ferrocene (E)-5 by powder sodium hydroxide treatment. The molecular unit (E,E)-1-{beta-[4-(beta-(1?-formylferrocenyl)-ethenyl)-phenylethynyl]-phenyl]-ethenyl}-1?-formylferrocene, (E,E)-6, was synthesized by palladium catalyzed cross-coupling between the p-iodophenyl derivative (E)-2 and their ethynyl derivative (E)-5, in good yield. The (E,E)-1,1?-(p-iodophenyl)ethenyl ferrocene, (E,E)-7, was synthesized by reaction between 1,1?-diformylferrocene and the p-iodobenzyltriphenylphosphonium ylid, as a mixture of isomers which were purely isolated. Moreover, isomerization of the Z,Z and E,Z mixture to the E,E isomer, was induced by sunlight exposure, catalyzed by iodine, in quantitative yield. The (E,E)-1,1?-[beta-(4-ethynylphenyl)-ethenyl]ferrocene, (E,E)-10, was synthesized in good yield, by palladium catalyzed cross-coupling of compound (E,E)-7 with 2-methyl-but-3-yn-2-ol, followed by powder sodium hydroxide treatment.

The N-alkylation of sulfonamides with alcohols in water catalyzed by the water-soluble iridium complex {Cp*[6,6′-(OH)2bpy](H 2O)}[OTf]2

The water-soluble iridium complex {Cp*[6,6′-(OH)2bpy] (H2O)}[OTf]2 (Cp=nu5-pentamethylcyclopentadienyl, bpy=2,2′-bipyridine) was found to be a general and highly efficient catalyst for the Nalkylation of the poor nucleophilic sulfonamides with alcohols as alkylating agents in water. The presence of OH units in the bpy ligand is crucially important for the catalytic activity of the iridium complex. Mechanistic investigations revealed that the catalytically active species is a ligand-metal bifunctional iridium complex bearing an N,N’-chelated 2,2′-bipyridinated ligand and an aqua ligand. Notably, the present catalytic system and the proposed mechanism provide a new horizon and scope for the development of “hydrogen autotransfer (or hydrogen-borrowing) processes”.

Benzothiadiazole-based organic dyes with pyridine anchors for dye-sensitized solar cells: Effect of donor on optical properties

Abstract New dyes containing pyridine anchoring group and different nitrogen-based heterocyclic electron-donating units linked via benzothiadiazole moiety have been synthesized and characterized by photophysical studies. Incorporation of benzothiadiazole extended the absorption onset into the lower energy region up to 600 nm. The dyes possessing vinyl linker between the heterocyclic donor and benzothiadiazole exhibited red-shifted absorption with high molar extinction coefficient than the dyes, which contain heterocyclic donor directly attached to the benzothiadiazole unit. The dyes exhibited acidochromism in the absorption spectra presumably due to the protonation of the pyridine nitrogen. These materials exhibited good thermal stability and their thermal-decomposition temperatures are in the range, 355-407 C. The dye-sensitized solar cells fabricated using a dye containing phenothiazine donor showed power conversion efficiency of 1.97%. Electrochemical impedance studies reveal that the charge separation is highly dependent on the structural composition of the dyes.

The conversion of 1,1?-dibromoferrocene to 1,2-dibromoferrocene: The ferrocene-chemist’s dream reaction

The conversion of 1,1?-dibromoferrocene to a range of 2-substituted bromoferrocenes is described. The products are useful in the preparation of a wide number of 1,2-disubstituted ferrocenes. This includes the preparation of 1,2-dibromoferrocene and 2-(diisopropylphosphino)bromoferrocene in what is a clean and simple synthesis. The synthesis may be carried out on a large scale and for the first time produces multigram quantities of these important precursor compounds. In addition the synthetic procedure may be modified to produce a new family of ferrocene-based tris-phosphine ligands such as bis(2-diphenylphosphinoferrocenyl)phenylphosphine.

Highly Diastereo- and Enantioselective Synthesis of Nitrile-Substituted Cyclopropanes by Myoglobin-Mediated Carbene Transfer Catalysis

A chemobiocatalytic strategy for the highly stereoselective synthesis of nitrile-substituted cyclopropanes is reported. The present approach relies on an asymmetric olefin cyclopropanation reaction catalyzed by an engineered myoglobin in the presence of ex situ generated diazoacetonitrile within a compartmentalized reaction system. This method enabled the efficient transformation of a broad range of olefin substrates at a preparative scale with up to 99.9 % de and ee and up to 5600 turnovers. The enzymatic product could be further elaborated to afford a variety of functionalized chiral cyclopropanes. This work expands the range of synthetically valuable, abiotic transformations accessible through biocatalysis and paves the way to the practical and safe exploitation of diazoacetonitrile in biocatalytic carbene transfer reactions.
