Palladium-catalyzed alkynylthiolation of alkynes with triisopropylsilylethynyl sulfide

Regio- and stereoselective addition of a silyl-substituted alkynyl sulfide to various terminal alkynes proceeds in the presence of a palladium catalyst to give (Z)-1-thio-1,3-enynes, which are useful building blocks for the synthesis of polysubstituted 1,

Selective synthesis of (Z)-chalcogenoenynes and (Z,Z)-1,4-bis-chalcogenbuta-1,3-dienes using PEG-400

We present here our results on the temperature controlled, selective hydrochalcogenation of 1,4-diorganyl-1,3-butadiynes with nucleophilic species of selenium, tellurium and sulfur generated in situ from the respective diaryl dichalcogenide and NaBH4

Hydrochalcogenation of symmetrical and unsymmetrical buta-1,3-diynes with diaryl dichalcogenides: Facile entry to (Z)-1-(organylchalcogeno)but-1-en-3-yne derivatives

This work describes an efficient and stereoselective method for the hydrothiolation and -selenation of buta-1,3-diyne derivatives using diaryl disulfides or diselenides, respectively. In the presence of rongalite (HOCH2SO2Na) and potassium carbonate, buta-1,3-diynes undergo stereoselective addition of the thiolate or selenide anion generated in situ from diaryl disulfides or diselenides to afford the corresponding (Z)-1-sulfanyl- or (Z)-1-selanylalk-1-en-3-yne derivatives, respectively. The reaction of buta-1,3-diynes with diaryl disulfides or diselenides at higher temperature (70 °C) gave a mixture of monothiolation/selenation and bisthiolation/selenation products in moderate to good yields.

Synthesis of (Z)-organylthioenynes using KF/Al2O 3/solvent as recyclable system

PEG-400 and glycerol were successfully used as recyclable solvents for the synthesis of several organylthioenynes in good to excellent yields and high selectivity using solid supported catalyst (KF/Al2O3). This easy, general and impr

A novel stereoselective preparation of various vinyl sulfide derivatives using β-alkylthioalkenylselenonium salts

The treatment of alkynylselenonium salt and various thiophenol derivatives with a catalytic amount of triethylamine gave β-arylthioalkenylselenonium salts in good yields. The alkenylselenonium salts thus prepared reacted with nucleophiles such as acetylides, thiolates, and alkoxides to produce (Z)-β-arylthio-α-functionalized ethenes in high yields. The vinylselenonium salts bearing a hydroxy group on a β-side chain caused intramolecular cyclization upon treatment with sodium hydride to produce medium-membered heterocyclic compounds containing sulfur and oxygen atoms. The reactions giving (Z)-β-arylthio-α-functionalized ethenes would proceed via the formation of selenurane intermediates followed by the ligand coupling reaction.
