Application

3-Ethoxy-3-oxopropylzinc bromide is a reagent used to insert ethyl propanoate group to the substrate. It can be used in:
  • Synthesis of γ-keto esters from aryl chlorides.
  • Synthesis of sulfones from 1,4-diazabicyclo[2.2.2]octane bis(sulfur dioxide) (DABSO) and alkyl halides.
  • Negishi cross-couplings with aryl vinyl phosphates to synthesize 1,1-disubstituted alkenes.
