Hexafluoroisopropanol (HFIP)-promoted disulfidation and diselenation of C-C unsaturated bonds is reported. Reactions of unactivated alkyne, alkene, and allene, respectively, with disulfides or diselenides in HFIP led to desired products in good to excellent yields (up to 96percent). In contrast, other solvents, such as isopropanol and dichloroethane, could not promote the same reaction. This method revealed an example of HFIP-promoted transformations under the mild conditions, which greatly highlighted the unique reactivity of this special solvent.

A novel disulfenylation of alkenes with thiophenols and their corresponding disulfides by using air as the oxidant has been achieved. This transformation provides a facile and practical protocol for the synthesis of vicinal dithioethers under mild conditions.

The bis(triflimide)iron(III) salt catalyzes the hydrothiolation of styrenes in a Markovnikov fashion with good selectivities and high yields. After isolation, different benzylic thioethers are obtained. This iron(III) catalyst is unique in terms of regioselectivity and represents a sustainable and economic alternative to those processes based on stoichiometric reagents. Copyright
Iodine-catalyzed disulfidation of alkenes
Wang, Xiu-Ren,Chen, Fan
experimental part, p. 4547 - 4551 (2011/07/08)
The disulfidation reactions of alkenes with disulfides were thoroughly investigated in this paper. Using H2O or DCE as the solvent, most reactions occurred smoothly to give the corresponding disulfidated products in good to high yields at room temperature within 12 h.

Dellus, Nicolas,Kato, Tsuyoshi,Bagan, Xavier,Saffon-Merceron, Nathalie,Branchadell, Vicenc,Baceiredo, Antoine
supporting information; experimental part, p. 6798 - 6801 (2010/12/19)
Heart of carbon: The first stable asymmetric bis(ylide), N,N'-(iPr 2NCH2CH2NiPr) (Ph) P-C-SPh2, has been isolated (see picture; C black, N gray). The presence of the two different ligands causes this carbon (0)
Thiolysis of 1,2-epoxides by thiophenol catalyzed under solvent-free conditions

, p. 6785 - 6787 (2007/10/03)
Thiolysis of alkyl- and aryl-1,2-epoxides was investigated under solvent-free conditions in the presence of Lewis and Br?nsted acid and base catalysts (InCl3, p-TsOH, n-Bu3P, K2CO3). Five mol% of catalyst was su
