Abstract
Oxiranes and sodium p-toluene sulfinate salt react smoothly in a regioselective manner in the presence of PEG4000 to furnish β-hydroxy sulfone and β-hydroxysuifide. The reaction was extended for the preparation of alkylsulfones and β-oxosulfones from alkylhalide and β- oxohalide respectively.
