Abstract
A new protocol for the β-sulfonation of α,β-unsaturated carbonyl compounds is described. The method employs FeCl3 as catalyst and TMSCl as additive for conjugate addition of sodium p-toluenesulfinate to enones.
Key words
β-sulfonyl ketones - conjugate addition - α,β-unsaturated carbonyl compounds - iron(III) chloride - trimethylsilyl chloride
