title: Taming the carboxyl group for directed carbometalation: observations on the use of anions, dianions and ester enolates.
abstract: Carboxylate anions, dianions and ester enolates provide simultaneous protection and activation for directed carbometalation reactions. Advantage can be taken of the bis-carbanionic character of the intermediate for further controlled C-C bond forming reactions.
