Synthetic and electrochemical studies on electroactive ionophores based on the di-η-cyclopentadienyl-molybdenum and -tungsten fragments

The compound reacts with HSCH2(CH2OCH2)3CH2SH in the presence of base giving the metalla-crown ether complex which can undergo a reversible one-electron oxidation.Treatment of (M=Mo or W) with 4'-carboxybenzo-15-crown-5 and base gives the complexes 2>, which also undergo reversible oxidation.Small changes in the E1/2 (2> (M=Mo or W) prepared from the sodium salt of (benzo-15-crown-5) -4'-thiol and , undergo a reversible one-electron oxidation and the E1/2 is shifted anodically upon addition of alkali metal cations.

Application of HPLC for the screening of separation of new macrocyclic systems

The efficient synthesis of new macrocyclic systems via nucleophilic ring opening reaction of epoxides by thiols was described. Initially new macrocyclic compounds were obtained as a mixture of diastereomers. Preparative thin layer chromatography was applied to separate meso and pairs of enantiomer. The identification of products using a chiral HPLC column and mass spectroscopy was utilized.

Optimized methods for preparation of 6I-(ω-sulfanyl-alkylenesulfanyl)-β-cyclodextrin derivatives

A general high-yielding method for the preparation of monosubstituted β-cyclodextrin derivatives which have attached a thiol group in position 6 is described. The thiol group is attached through linkers of different lengths and repeating units (ethylene glycol or methylene). The target compounds were characterized by IR, MS and NMR spectra. A simple method for their complete conversion to the corresponding disulfides as well as a method for the reduction of the disulfides back to the thiols is presented. Both, thiols and disulfides are derivatives usable for well-defined covalent attachment of cyclodextrin to gold or polydopamine-coated solid surfaces.

Amphiphilic silicone architectures via anaerobic Thiol-Ene chemistry

Despite broad application, few silicone-based surfactants of known structure or, therefore, surfactancy have been prepared because of an absence of selective routes and instability of silicones to acid and base. Herein the synthesis of a library of explic

Synthesis and extraction properties of oxathiacrown compounds containing benzyl groups

8-Benzyl-1.4-dioxa-7,10-dithiacyclododecane and 11-benzyl-1,4,7-trioxa-10, 13-dithiacyclopentadecane were obtained by the interaction of (2,3-dibromo-1-propyl)benzene with 1,8-dimercapto-3,6-dioxaoctane and 1,11-dimercapto-3,6,9-trioxaundecane. The extrac

The synthesis and complexation studies of thia-anthracene receptors

Systematic studies towards the formation of thia-anthracene receptors were performed. Anthracene podand 3 consisting of two anthryl groups connected by the SCH2CH2CH2S spacer group was prepared in 99% yield. The complexation properties of this compound were investigated using UV-VIS and fluorescence titration techniques. Addition of silver salts into a solution of the fluorophore strongly modifies the absorption and fluorescence spectra and the association constants were found to be K1 = 2 x 105 and K2 = 8 x 104 M-1 for the 1:1 and 1:2 complexes, respectively. Addition of metal ions, as Cu2+ Zn2+, Cd2+, Hg2+, Ni2+, and Co2+, did not lead to any change in the photophysical properties of compound 3.

Process for the preparation of 2-mercaptoalkyl-sulphides and 2-mercaptoalkylethers

2-Mercaptoalkylsulphides and 2-mercaptoalkylethers are obtained by the hydrazinolysis of 3-thiaalkylisothiuronium salts and 3-oxaalkylisothiuronium salts.
