• thiyl-radical-mediated reactions have been extensively investigated for the preparation of carbohydrate derivatives [20] and some dithioether phospholipid and glycolipid analogues [21][22], no examples were reported for the synthesis of n-alkyl thioglycosides by using thiol–ene coupling [18][19]. In

• coupling of thiols with alkynes gave 1,2-dithioether. Later that year, Yadav and co-workers reported a new photoredox-catalyzed method for the preparation of β-ketosulfoxides (Scheme 6) [36]. The reaction proceeds again via a radical thiol–ene pathway, but oxygen plays a key role in this reaction. The

• allyl bromide with excess thiol at room temperature is described. The choice of silica gel, either pre-calcined or moistened with water, exhibited notable regioselectivity in the formation of dithioethers. Plausible mechanistic routes were explored and postulated.

• and also as spacers in metal-organic frameworks [9][10][11][12][13][14]. For example, vicinal dithioether-based zirconium and titanium complexes have been used for alkene polymerization and hydroamination [15][16][17][18]. Chiral dithioethers have been prepared and their iridium complexes have been

• by silica NPs, where a single example of a reaction of an allyl bromide and excess benzenethiol was studied [41][42]. The reaction was carried out in the presence of silica NPs and water, and they isolated 1,3-dithioether by an anti-Markovnikov addition. However, there is no report on the metal-free

The reaction of either dibromide with α-mercaptoacetophenone in the presence of 2,6-lutidine yields dithioether intermediates 7 and 8. Oxidation of
