Electronic properties of para-substituted thiophenols and disulfides from 13C NMR spectroscopy and ab initio calculations: relations to the Hammett parameters and atomic chargesElectronic supplementary information (ESI) available: all characterization data are tabulated in Table S1. A figure showing the dependence of the natural charge of the C1 atom of the disulfides on the 13C NMR chemical shift is also provided. See http://www.rsc.org/suppdata/nj/b3/b300048f/

Design, synthesis, and characterization of a sterically encumbered dioxo molybdenum (VI) core

“…24 We anticipate that the electronic nature of the 2 nd generation ligand is similar to that of the 1 st generation, and also the electronic structures of the metal centers in these molecules do not change appreciably and the electrophilicity of the terminal oxo-groups remain invariant. Therefore, the difference in the reactivity of between PPh 3 and PEt 3 with 6(c) may be attributed to two major factors -nucleophilic control arising from a difference in the basicity of the phosphines and steric control arising the size of the phosphines as well the ligands architecture surrounding the molybdenum center.…”

“…23 The G1-ester dendron (3-[2-amino-3-(2-ethoxycarbonyl-ethoxy)-2-(2-ethoxycarbonyl-ethoxymethyl)-propoxy]-propionic acid ethyl ester), compounds 1 and 2 were prepared by following the procedures described earlier. 24 All work up and chromatographic purifications of complexes were conducted in air using distilled solvents. The solvents were purified as follows: methylene chloride (CH 2 Cl 2 ) from CaH 2 ; tetrahydrofuran (THF) from Nabenzophenone; acetonitrile from CaH 2 followed by Li 2 CO 3 -KMnO 4 and finally from P 2 O 5 ; methanol (MeOH) and ethanol was purified from Mg. Triethylamine and pyridine were dried by distilling over KOH pallets.…”

“…Synthesis of zero and first generation of disulfide molecules have been published elsewhere. 24 The second generation of disulfide ligand 4, was synthesized by hydrolyzing the ester functionality of the first generation disulfide 1 with ethanolic solution of sodium hydroxide. The completion of the hydrolysis reaction and formation of 3 was confirmed by ensuring the complete absence of the ester signals in 1 H NMR spectra.…”

Turn‐On and Selective Luminescence Sensing of Copper Ions by a Water‐Soluble Cd10S16 Molecular Cluster

“…Cluster 2 was prepared by the ligand-exchange reaction of 1 [7] with 4-OEG-modified thiophenol (HSC 6 H 4 (OC 2 H 4 ) n OCH 3 ), which was prepared by coupling 4,4'-dihydroxydiphenyl disulfide [13] with the tosylate ester of poly(ethylene glycol) methyl ether (M n % 350) followed by NaBH 4 reduction. The thiol (2.4 mmol) was added to a solution of 1 (50 mg) in MeCN (0.020 mmol/20 mL), and the mixture was heated at 60 8C for 6 h. After removal of the solvent, the residue was washed copiously with ether to give 2 as a tan solid (113 mg, 95 %).…”

Thiosaccharine disulfide: Synthesis, crystal structure, spectroscopic characterization and theoretical study

“…They have also reducing character of both metal ions and other species. The chemical oxidation of the thiols usually leads to the corresponding organic disulfides [1][2][3][4]. The study of organic disulfides is of continuous interest, because it is related to the redox behavior of proteins in natural systems containing the cysteine amino-acid which can be oxidized with the concomitant disulfide production [3,[5][6][7].…”
