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
Synthesis of divinylsulfides

experimental part, p. 947 - 952 (2010/04/30)
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.

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.

A study was carried out on the reaction of acetylene, phenylacetylene and vinylacetylene with sodium sulfide, thioacetic acid, and water (in the case of acetylene) in a triethylphosphine oxide-KOH superbase system.In the nature of its effect on the nucleophilic addition to acetylenes, the triethylphosphine oxide-KOH system is similar to the dimethylsulfoxide-KOH and hexamethylphosphorotriamide-KOH systems.
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.
