Diaminomethylenemalononitrile organocatalysts promote the asymmetric chlorination of simple cyclic β-keto esters such as methyl, ethyl, and benzyl esters of 1-oxo-2,3-dihydro-1H-indene-2-carboxylic acid. This affords the corresponding chiral α-chlorinated
Oxidative Chlorination of Activated Methylene Compounds with Sodium Chloride

An operationally simple protocol for the direct chlorination of 1,3-dicarbonyls (and related compounds such as α-cyano A?ketones) is described. The procedure relies on mild conditions using IBX-SO3K as the stoichiometric oxidizing agent and the
Sulfoxide-mediated Umpolung of alkali halide salts

A new protocol for the direct two-electron oxidative Umpolung of alkali halide salts is reported. This procedure, relying on the use of a commercially available sulfoxide as the oxidant, allows the electrophilic halogenation of carbonyl compounds as well as halolactonisation reactions to proceed from the corresponding sodium salts, at room temperature and under mild conditions.
