A process for condensing at least one carbonyl compound carrying at least one electron-withdrawing group with an aromatic derivative carrying at least one hydroxyl functional group, wherein the electron-withdrawing group present on the carbonyl compound is selected from fluoroalkyl derivatives, esters, including orthoesters, and nitriles and said condensation is carried out in a basic medium.

Un proceso para condensar por lo menos un compuesto de carbonyl que lleva por lo menos a un grupo electro'n-que se retira con un derivado aromático que lleva por lo menos un grupo funcional del oxhidrilo, en donde seleccionan al grupo electro'n-que se retira presente en el compuesto de carbonyl de derivados del fluoroalkyl, los ésteres, incluyendo orthoesters, y los nitriles y condensación dicha se realiza en un medio básico.
