Simple and inexpensive polyhalides (CCl4 and C2Cl6) have been found to be effective and versatile oxidants in removing electrons from Breslow intermediates under N-heterocyclic carbene (NHC) catalysis. This oxidative react

Carbenes ring true: N-Heterocyclic carbene (NHC) catalyzed reactions of α-bromo-α,β-unsaturated aldehydes/α,β- dibromoaldehydes with 1,3-dinucleophilic reagents, such as 1,3-dicarbonyl compounds, β-enamino ketones, and β-enamino esters through umpolung processes gave functionalized 3,4-dihydropyranones and 3,4-dihydropyridinones (see scheme). The availability of the starting materials, lack of external oxidant, and usefulness of the products make this strategy attractive.

Through oxidative carbene catalysis the reactivity of enals can be reversed at the β position from the typical electrophilic to nucleophilic (homoenolate chemistry) further to electrophilic reactivity by two consecutive umpolung processes. These redox-act
