A transition-metal-free t -BuOK-mediated reductive C-P cross-coupling reaction of arylvinyl sulfides with diarylphosphine oxides through C-S bond cleavage has been developed. This protocol not only permits the synthesis of diaryl(2-arylethyl)phosphine oxides, but also achieves an unprecedented construction of a C-P bond through C-S bond cleavage and reduction of a C-C double bond in one pot.
Amberlyst-15: An efficient heterogeneous reusable catalyst for selective anti-Markovnikov addition of thiols to alkenes/alkynes and for thiolysis of epoxides

The anti-Markovnikov addition of thiols to alkenes/alkynes and thiolysis of epoxides is described using Amberlyst-15 as a selective, commercially available, inexpensive and reusable catalyst. The products like diorganyl sulphides, β-hydroxy sulphides and phenyl(styryl)sulfanes were obtained in good to excellent yields in short reaction time and with high regio-selectivity. The catalyst was reused up to five consecutive recycles without any loss in its catalytic activity. The developed methodology is a metal free protocol for C-S bond formation reaction with high atom economy.

A novel method for the synthesis of vinyl sulfides by the decarboxylative cross-coupling of arylpropiolic acids with thiols using copper(I) salts as catalysts has been developed. In the presence of CuI and Cs2CO 3, a variety of thiols reacted with arylpropiolic acids to afford the corresponding vinyl sulfides in good to excellent yields with high stereoselectivity for Z-isomers.
Regio- and stereoselective synthesis of vinyl sulfides via PhSeBr-catalyzed hydrothiolation of alkynes
Manarin, Flávia,Roehrs, Juliano A.,Prigol, Marina,Alves, Diego,Nogueira, Cristina W.,Zeni, Gilson
, p. 4805 - 4808 (2008/02/05)
We present here a simple and mild method of hydrothiolation of internal and terminal alkynes under PhSeBr-catalyzed reaction in the absence of solvent at room temperature. The reaction tolerates a wide variety of substituents on thiol, and provides the co
Mild, efficient and highly stereoselective synthesis of (Z)-vinyl chalcogenides from vinyl bromides catalyzed by copper(I) in ionic liquids based on amino acids
