Krapcho decarboxylation

Krapcho decarboxylation

The Krapcho decarboxylation is the chemical reaction of esters with halide anions. The ester must contain an electron-withdrawing group in the beta position, such as β-ketoesters, malonic esters, α-cyanoesters, or α-sulfonylesters. [Krapcho, A. P.; Glynn, G. A.; Grenon, B. J.
