Tributylstibine can mediate the olefination of car-bony1 compounds with bromomalonic ester and with dibromomalonic ester. An initial halophilic attack of tributylstibine on the bromine of bromomalonic or dibromomalonic ester forming an ion pair of bromotributvlstibonium cation and malonic ( A ) or b
