4,4′-diarylsulfanyl-2,2′,5,5′-tetraoxybiaryl derivatives as a water-soluble fluorescent dye

4,4′-Disulfanyl-2,2′,5,5′-tetrahydrobiaryl (5,5′-disulfanyl hydroquinone dimer) derivatives were readily synthesized from benzoquinone and thiols via an oxidative coupling reaction. The hydroquinone dimers showed strong fluorescence upon excitation at 330

Facile synthesis of quinone dimer derivatives substituted with sulfanyl groups and their properties

Quinone dimers are readily prepared quantitatively from 2- sulfanyl-1,4-dimethoxybenzene by oxidative treatment. The oxidative coupling progressed in a highly regioselective manner. Removal of O-protection and subsequent oxidation gave 5,5'- bis(sulfanylquinone) dimer in good yields. Physical properties of the dimer derivatives are also investigated.

FeCl3-mediated direct chalcogenation of phenols

Direct sulfenylation and selenylation of phenols using a stoichiometric amount of FeCl3 under an oxygen atmosphere has been developed. The chalcogenated phenols were shown to be suitable for preparing S- and Se-containing compounds using the reaction of the remaining hydroxy group.

Polymer-supported hypervalent iodine reagents in 'clean' organic synthesis with potential application in combinatorial chemistry

A clean oxidation reaction of a variety of substrates using polymer-supported (diacetoxyiodo)benzene (PSDIB) which proceeds in high to excellent yield with maximum purity is described including isolation and regeneration of the polymer reagent.

PHOTOCHEMICAL DESULPHURIZATION OF PHENOLIC THIOETHERS, THIOLS AND DISULPHIDES

Photolysis of alkylthiodihydroxybenzenes 2-4 and the related thiols 5, 6, 8 and disulphide 7 under argon proceeds with partial desulphurization to give the parent hydroxybenzenes in 13-36percent yield.Under the same conditions, benzenethiol, 9, decomposes slowly to give low amounts of benzene.Irradiation of sulphides 10 and 11 results in the selective cleavage of the C-S bond on the hydroxy- or methoxy-substituted ring to yield the desulphurized products in more than 60percent yield.

A new method for the preparation of Michael adducts and cyclic enones using lithium chloride-hexamethylphosphoramide system

A new procedure using lithium chloride in hexamethylphosphoramide was found to be useful for the synthesis of Michael-type adducts and cyclic enones. Selectivity for the two products could be controlled by altering the reaction temperature employed. The urea-type solvents were also examined instead of hexamethylphosphoramide.

Synthesis of 5-Anilino-2-phenylthio-1,4-benzoquinones

Reductive addition of substituted anilines to 2-phenylthio-1,4-benzoquinone followed by oxidation of a second molecule of the quinone, affords a series of 5-amino-2-thio-substituted 1,4-benzoquinones in good yields.

Lewis Acid Catalyzed Cycloreversion Reaction of Strained Cage Ketones to Triquinane Skeletons: Kinetic Evidence for a Large Acceleration of the Reaction Owing to Stereoelectronic Requirement

Cookson's pentacyclic cage diketones substituted with an electron-donating group (1b-e) underwent a remarkably fast cycloreversion reaction under various Lewis acid catalyzed conditions.The high reactivity of these cage ketones is discussed in terms of push-pull type interactions on the basis of large substituent effects and kinetic measurements.Keywords - cycloreversion reaction; Cookson's pentacyclic cage diketone; Lewis acid catalyst; electron-donating group; stereoelectronic effect
