Facile Conversion of Epoxides to 1,2-Diacetates with NaOAc•3H2O/Ac2O System
This study represents a highly efficient and regioselective ring-opening of epoxides with acetic anhydride in the presence of NaOAc<span style="font-size: 10.0pt; font-family: 'Times ...
متن کاملDisulfide 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...
