TL;DR: In this article, the metal chlorides with the mercaptan in organic solvents were synthesized by reaction of metal chloride with the Mercaptan, and the compounds were investigated by different methods.
Abstract: 1:1-Komplexe des Bis-(2-mercaptoathyl)-athers wurden durch Reaktion der Metallchloride mit dem Mercaptan in organischen Losungsmitteln erhalten. Die Verbindungen wurden mit chemischen Methoden und durch IR-, 1H-NMR- und Massenspektren charakterisiert.

TL;DR: This article showed that tricyclic ketones 3 and 4 were products of intramolecular Diels-Alder addition in the intermediate 2,4,6-trimethyl-6-(penta-2,4-dienyl)-cyclohexa2, 4dien-1-one.
Abstract: Thermal rearrangement of trans-penta-2,4-dienyl mesityl ether (trans-1) gave, besides trans, cis-2 and trans, trans-2, the homotwistanone derivative 1,3,10-trimethyl-tricyclo[5.4.0.03,9]undeca-5,10-dien-2-one (3) as well as its isomer 1,3,9-trimethyl-tricyclo[5.3.1.03,8]undeca-5, 9-dien-2-one (4). The tricyclic ketones 3 und 4 were shown to be products of intramolecular Diels-Alder addition in the intermediate 2,4,6-trimethyl-6-(penta-2,4-dienyl)cyclohexa-2,4-dien-1-one (5). Preparation of 2,6-methyl-6-(3-methyl-penta-2,4-dienyl)-cyclohexa2,4-dien-1-one (6) and subsequent heating of 6 in benzene gave the homotwistanone derivative 1,3-6-trimethyl-tricyclo5.4.0.03,9]undeca-5,10-dien-2-one (7) together with its isomer 1,3,6-trimethyl-tricyclo[5.3.1.03,8]undeca-5,9-dien-2-one (8) in good yield.

TL;DR: In this article, the acid-catalyzed ring-opening of aryl-substituted epoxides by alcohols to form β-hydroxy ether products was investigated.
Abstract: Polymers containing electrophilic moieties, such as activated esters, epoxides, and alkyl halides, can be readily modified with a variety of nucleophiles to produce useful functional materials. The modification of epoxide-containing polymers with amines and other strong nucleophiles is well-documented, but there are no reports on the modification of such polymers with alcohols. Using phenyloxirane and glycidyl butyrate as low molecular weight model compounds, it was determined that the acid-catalyzed ring-opening of aryl-substituted epoxides by alcohols to form β-hydroxy ether products was significantly more efficient than that of alkyl-substituted epoxides. An aryl epoxide-type styrenic monomer, 4-vinylphenyloxirane (4VPO), was synthesized in high yield using an improved procedure and then polymerized in a controlled manner under reversible addition-fragmentation chain-transfer (RAFT) polymerization conditions. A successful chain extension with styrene proved the high degree of chain-end functionalization of the poly4VPO-based macro chain transfer agent. Poly4VPO was modified with a library of alcohols and phenols, some of which contained reactive functionalities, e.g., azide, alkyne, allyl, etc., using either CBr4 (in PhCN at 90 °C for 2–3 days) or BF3 (in CH2Cl2 at ambient temperature over 30 min) as the catalyst. The resulting β-hydroxy ether-functionalized homopolymers were characterized using size exclusion chromatography, 1H NMR and IR spectroscopy, and thermal gravimetric analysis. © 2015 Wiley Periodicals, Inc.

TL;DR: Phenolic sesquiterpenes including 6-(2-hydroxy-4-methylphenyl)-2-methyl-3-heptanone, and curcuphenol methyl ether have been obtained from oxidative cleavage of bicyclic precursors by treatment with acidic hydrogen peroxide in a process which probably parallels a biogenetic step as discussed by the authors.

TL;DR: Sodium iodide complexes of 16-membered dibenzo-azocrown and azoxycrown ethers have been synthesized and their structures determined by X-ray method as mentioned in this paper.
Abstract: Sodium iodide complexes of 16-membered dibenzoazocrown ether (complex I) and dibenzoazoxycrown ether (complex II) have been synthesized and their structures determined by X-ray method Stoichiometry of both complexes is 1:1 (ligand: salt); the cation is coordinated to oxygen atoms of the oxyethylene moieties and to one nitrogen atom of azo group in the first, or to oxygen atom of the azoxy group in the last complex Selectivities of membrane electrodes doped with ion carriers, including 16-membered azocrown and azoxycrown ethers have been compared and discussed mainly in terms of features of crystal structures of carrier complexes
