Shen, Chaoren,Spannenberg, Anke,Wu, Xiao-Feng
, p. 5067 - 5070 (2016/04/26)
Multicomponent reactions, especially those involving four or even more reagents, have been a long-standing challenge because of the issues associated with balancing reactivity, selectivity, and compatibility. Herein, we demonstrate how the use of a reagen

Convenient Horner-Wittig-based synthetic approaches to the preparation of (diphenylphosphinoyl)methyl vinyl sulfides as well as symmetrically and unsymmetrically substituted divinyl sulfides, are described. The syntheses involve the use of the easily avai

Arylacetylenes react with sodium sulfide in the presence of water to yield divinylsulfides. The reaction proceeds in good to excellent yield for both electron-neutral and electron-deficient aromatic systems; for electron-rich aryls, longer reaction times are necessary. The sulfides represent useful substrates for further transformations, for example, oxidation to the corresponding divinylsulfoxides and divinylsulfones. Three selected divinylsulfide derivatives were oxidized selectively to the corresponding sulfoxides or sulfones. Georg Thieme Verlag Stuttgart ? New York.

A variety of 2-mercapto-substituted vinyl radicals have been produced through the free-radical reaction of alkanethiols (including phenethyl, allyl, and benzyl mercaptans) with monosubstituted acetylenes in benzene at 90 deg C.The 2-(benzylthio)vinyl radi

, p. 470 - 475 (2007/10/02)
A method for the production of Z-2-benzylidene-4-phenyl-1,3-diselenole was worked up on the basis of an investigation into the effect of the process parameters on the yields of the products from the reaction of metallic selenium with phenylacetylene.
SINGLE-STAGE SYNTHESIS OF VINYL SULFIDES FROM HALOGEN DERIVATIVES, ACETYLENES, AND SODIUM SULFIDE
Nosyreva, V. V.,Amosova, S. V.,Trofimov, B. A.
, p. 1770 - 1774 (2007/10/02)
The vinylthiylation of halogen-containing compounds by acetylenes in the presence of sodium sulfide was realized.The effect of the ratio of ethylene chlorohydrin and sodium sulfide, the concentration of water, the order in which the initial reagents are mixed, and the reaction temperature on the yield of the vinyl sulfides was investigated.
A CONVENIENT PREPARATION OF Z-STYRYL, Z,Z- AND E,Z-DISTYRYL SULFIDES IN LIQUID AMMONIA

Nucleophilic attack of thiols on phenylacetylene (1) in liquid ammonia at room temperature gave the corresponding Z-isomer of styryl sulfides in high yield stereoselectively.Reaction of 1 with Na2S also proceeded selectively to give Z,Z-distyryl sulfide (12).On the other hand, reaction with NaSH gave 12 besides E,Z-isomer as a minor product.
HIGH-TEMPERATURE ORGANIC SYNTHESIS. XVIII. REACTION OF HYDROGEN SULFIDE WITH α- OR β-BROMOSTYRENE

The thermal condensation of α- or β-bromostyrene with hydrogen sulfideis realized in the liquid phase at 145-180 deg C and leads mainly to 2,4-diphenylthiophene.The latter is formed from α-bromostyrene with yields of 32-37percent with a low concentration of hydrogen sulfide and from β-bromostyrene with a high concentration of hydrogen sulfide.At 130-140 deg C bis sulfides are formed in addition to 2,4-diphenylthiophene, and they do not undergo cyclization to diphenylthiophenes under the reaction conditions.In addition to the sulfur-containing compounds, the products from the reaction of bromostyrenes with hydrogen sulfide include aromatic hydrocarbons: styrene and also 1-phenylnaphthalene from α-bromostyrene and 2-phenylnaphtalene from β-bromostyrene.In the gas phase at 500-600 deg C the main product from the reaction of bromostyrenes with hydrogen sulfide is benzothiophene.
