Abstract Substituted perchlorobutadienes were synthesized from the reactions of hexachloro-1,3-butadiene with some thiols in ethanol in the presence of sodium hydroxide. The oxidation products were obtained from the reactions of thioethers with m-chloroperbenzoic acid. The structures of the new compounds were characterized by microanalysis and spectroscopic data.

Abstract Unprecedented high-yield simple and mild conversion of primary aliphatic and aromatic thioamides into 5-substituted tetrazoles on treatment with a combination of tetrachlorosilane and sodium azide in refluxing acetonitrile has been achieved. Secondary acyclic, cyclic, and heterocyclic thioamides could also be transformed in high yields into 1-substituted, 1,5-disubstituted, or annulated tetrazoles under the same reaction condition.

Abstract 2-Pyrimidinylidene-1,3-dithioles or 2-pyrazolylidene-1,3-dithioles are prepared by a three-component condensation reaction of pyrimidine-tetraone or 1H-pyrazole-4,5-dione, carbon disulfide, and dialkyl acetylendicarboxylates in the presence of tributylphosphine. GRAPHICAL ABSTRACT 相似文献

Abstract Asymmetric Michael-type Friedel–Crafts (F–C) alkylations of indoles with nitroolefins catalyzed by a chiral H8-BINOL-based phosphoric acid were investigated. The reactions took place very smoothly in the presence of only 5 mol-% of catalyst at room temperature to afford the desired F–C alkylation products in good yields and with moderate enantioselectivities.

Abstract A highly convenient method for the trimethylsilylation of alcohols and phenols via treatment by hexamethyldisilazane in the presence of melamine trisulfonic acid as a catalyst has been developed. A wide variety of hydroxyl groups were selectively protected under solvent-free conditions. GRAPHICAL ABSTRACT 相似文献

Abstract Photolysis of 2-(trimethylstannyloxy)-3,6-di-tert-butyl-benzquinone-1,4 (I), 2-(triphenylstannyloxy)-3,6-di-tert-butyl-benzquinone-1,4 (II), and 2-(tribenzylstannyloxy)-3,6-di-tert-butyl-benzquinone-1,4 (III) by light with the wavelength 436 nm leads to the evolution of carbon mono- and dioxide and the formation of hydrocarbon radicals with their consequent recombination.

Abstract Various substituted thiazolidin-2-ones were synthesized from the corresponding thiazolidine-2-thiones with bromoethanol in ethanol with sodium ethoxide as a base. The optimal reaction conditions and mechanism were reinvestigated in detail. The bioassay indicated that (S)-4-isobutyl and (S)-4-benzylthiazolidin-2-ones show certain inhibitive activities against Candida albicans and Escherichia coli.

Abstract In this work, the reactions of diphenylphosphinic chloride, (C6H5)2P(O)Cl, 1, with the sodium salts of sterically hindered phenol derivatives (2a-2j) were investigated. Novel alkyl-substituted aryl diphenyl phosphinate esters (C6H5)2P(O)OAr (3-12) were obtained from these reactions. Satisfactory analytical and spectroscopic results were obtained for all the new compounds. GRAPHICAL ABSTRACT 相似文献
