The selectivity of sulfonylation of β‐keto esters with sodium sulfinates under the action of iron(III) can be regulated by the solvent nature and reaction temperature. As a result, α‐sulfonyl β‐keto esters or α‐sulfonyl esters can be selectively obtained. Application of β‐diketones as starting materials gives only α‐sulfonyl ketones.
