Abstract

Procedimiento para la obtención de composiciones herbicidas de la fórmula general **fórmula** Los ácidos libres de la fórmula (i) , obtenidos mediante saponificación o preparación a partir de ácidos halogenpropiónicos (R4=OH), se pueden convertir posteriormente en otros ésteres de forma habitual. En este caso lo mejor es trabajar en presencia de cantidades catalíticas de ácido, como ácido sulfúrico, ácido toluensulfónico o ácido clorhídrico o en presencia de otros catalizadores ácidos. Como tales podemos señalar ácidos de Lewis como trifluoruro de boro o también intercambiadores ácidos de iones. Para la esterificación se pueden utilizar también los cloruros de ácido. Fácilmente accesibles mediante reacción de los ácidos carboxílicos de la fórmula (I) de cloruros de ácido inorgánicos con cloruro de tionilo, proporcionando los cloruros de ácido mencionados con los alcoholes señalados los ésteres correspondientes. Otros derivados de la fórmula(I) se obtienen mediante reacción de los cloruros de ácido o de ésteres con aminas o anilinas.
