A Ni-catalyzed C-S cross-coupling using only NiI 2 (0.5-2.5 molpercent) and P(O i Pr) 3 (2.0-10.0 molpercent) is reported. Using an air-stable Ni(II) precatalyst, and a cheap and commercially available ligand, a scalable and robust method was developed to cross-couple various thiophenols and styryl bromides, including some sterically encumbered thiols, an α-bromocinnamaldehyde as well as a thiolation-cyclization.

An example of a transition-metal-free, direct, and efficient acetamidosulphenylation reaction of alkenes using nitriles as the nucleophiles via a radical process is presented. This reaction shows a broad substrate scope and high regioselectivity and provides straightforward access to acetamidosulfide derivatives in moderate to high yields.

Tu, Hai-Yong,Hu, Bo-Lun,Deng, Chen-Liang,Zhang, Xing-Guo
supporting information, p. 15558 - 15561 (2015/10/28)
A copper and iodine-mediated C-H oxidative sulfenylation of olefins with diaryl disulfides has been developed for the stereospecific synthesis of vinyl thioether. With the combination of Cu(OTf)2 and I2, a variety of terminal alkenes
One-Pot Synthesis of 1-Alkenyl Sulfides from Alkynes and Organic Disulfides with the Use of Organoaluminums
Ramazanov, Ilfir R.,Kadikova, Rita N.,Zosim, Tatyana P.,Dzhemilev, Usein M.
, p. 2670 - 2676 (2015/09/01)
Organic disulfides (dipropyl, dihexyl, or diphenyl disulfide) are convenient and efficient agents for the sulfanylation of 1-alkenylaluminum derivatives.
THE REACTION OF ALKYL PHENYL SULPHIDES WITH MANGANESE DIOXIDE AND ACETYL CHLORIDE
Bellesia, Franco,Ghelfi, Franco,Pagnoni, Ugo Maria,Pinetti, Adriano
, p. 289 - 291 (2007/10/02)
In a one-pot reaction, manganese dioxide in stoichiometric amounts and acetyl chloride transform alkyl phenyl sulphides into the corresponding 1-alkenyl phenyl sulphides; these latter products can be undergo chlorination of the double bond promoted by the
A New Version of the Peterson Olefination Using Bis(trimethylsilyl)methyl Derivatives and Fluoride Ion as Catalyst
Palomo, Claudio,Aizpurua, Jesus M.,Garcia, Jesus M.,Ganboa, Inaki,Cossio, F. P.,et al.
, p. 2498 - 2503 (2007/10/02)
Reaction between a variety of bis(trimethylsilyl)methyl derivatives and carbonyl compounds under fluoride ion as catalyst is described.The reaction works especially well with nonenolizable carbonyl compounds to give the expected alkenes in high yields and, in some cases, with high stereoselectivity.Application of this methodology to an intramolecular alkenation providing a tricyclic benzocarbacephem ring system is also described.
