Abstract
Se describe un proceso para la preparacion de ésteres de 4,4'-estilbendicarboxilato por un proceso de 3 etapas utilizando ácido p-toluico, un p-formilbenzoato de alquilo y un fosfito trialquilo. Las etapas comprenden: (1) preparar el ácido p-(clorometil)benzoico clorado el ácido p-toluico con cloruro de sulfurilo en presencia de un iniciador de radicales libres y clorobenceno o diclorobenceno; (2) poner en contacto el ácido p-(clorometil)??banzoico de la etapa (1) con un fosfito trialquilo para obtener un compuesto fosfanato; y (3) poner en contacto el compuesto del éster fosfanato de la etapa (2) con un p-formilbenzoato de alquilo en presencia de un alcoxido de metal alcalino y un solvente inerte para obtener el 4,4'estilbendicarboxilato de dialquilo.
