Disulfide catalyzed the highly regioselective conversion of epoxides to halohydrins with elemental halogens
The regioselective ring opening of styrene oxide using elemental iodine and bromine in the presence of disulfides as new catalysts was studied. The conductivity titration and UV spectroscopy were used to study the interaction of iodine with these catalysts. The results indicate that disulfide 11 is efficient in polyiodide formation, and can catalyze this reaction in excellent yield and high reg...

متن کاملStereospecific Synthesis of Tri- and Tetrasubstituted α-Fluoroacrylates by Mizoroki-Heck Reaction.
Ligand-free, efficient, palladium-catalyzed Mizoroki-Heck reaction between methyl α-fluoroacrylate and arene or hetarene iodides is reported for the first time. The reaction is stereospecific and provides fair to quantitative yields of fluoroalkenes. The Mizoroki-Heck reaction starting from more hindered and usually reluctant trisubstituted acrylate, to access tetrasubstituted fluoroalkenes, is...

Poly (N-bromosuccinimide) (PNBS) as a mild, efficient, non-acidic, polymeric and heterogeneous catalyst was applied for simple conversion of epoxides into thiiranes by treatment with KSCN or (NH2)2CS at room temperature. Aliphatic and aromatic epoxides converted into their corresponding thiiranes under mild conditions. All reactions proceeded in short reaction times and afforded the correspondi...

Cellulose sulfuric acid is an efficient metal-free catalyst for the synthesis of 1,3,5-trisubstituted pyrazoles via the condensation of 1,3-diketones and hydrazines. The reaction was carried out in Solvent-free condition at room temperature and the products were isolated in good to excellent yields. Mild reaction conditions, as well as ease of operation and workup are some advantages of the pro...
