Descripción

Ethyl 2,2-dichloroacetoacetate is an aldehyde that can be used in the synthesis of other organic compounds. It is competitively converted to ethyl acetoacetate by reaction with sodium ethoxide. The ketone is then reduced with hydrogen chloride to give the desired product, acetoacetate, and hydrochloric acid. This compound crystallizes as a white solid, has a molecular weight of 96.14 g/mol and has a melting point of -41°C.
Ethyl 2,2-dichloroacetoacetate was reinvestigated and found to have an anion (Cl-) at the alpha carbon position on the molecule. The nmr spectrum does not show any signals for this ion due to its electronegativity. The proton nmr spectrum shows a singlet at 3.16 ppm corresponding to the hydroxide ion H3O+, which is consistent with the expected product from reduction
