title: Synthesis of alpha,alpha-dibromo esters as precursors of ynolates.
abstract: Aliphatic alpha,alpha-dibromo esters, precursors of ynolates, were synthesized via bromination of lithium alpha-bromo ester enolates with 1,2-dibromotetrafluoroethane in good yields. alpha-Trimethylsilyl-alpha,alpha-dibromo esters were synthesized via radical bromination.
