Abstract

Un proceso para preparar los ésteres 2-ciano-3,3-diarilacrílicos de la formula general I, en donde R1 y R2 son hidrogeno, grupos alquilo de C1-C12, grupos alcoxi de C1-C12 o grupos dialquil (de C1-C4)amino y R3 es un grupo alquilo de C4-C18 que puede ser interrumpido por átomos de oxígeno que funcionan comoéter, haciendo reaccionar una benzofenona imina de la formula general II, con un éster cianoacético de la formula general III, en donde la reaccion se lleva a cabo desde 20 a 60 degree C y, durante ésta, el amoniaco liberado se elimina continuamente de la mezcla de reaccion con la ayuda de una corriente de gas o reduciendo la presion de 900 a 100 mbar.
