Abstract

Se describe un proceso para la preparación de bencenos sustituidos o ácido bencensulfónico y sus derivados que comprende la diazotización de un aminobenceno o de un derivado del ácido orto-amino-bencensulfónico seguido por el acoplamiento homogéneo catalizado con paladio con una olefina y una hidrogenación heterogénea del sustituyente olefínico catalizada con paladio, en donde el catalizador homogéneo se reduce y se precipita como metal después de acoplarse en la mezcla de reacción y se utiliza como catalizador heterogéneo de paladio para el paso de la hidrogenación. El proceso es particularmente apropiado para la preparación de herbicidas de N-bencensulfon-N'-triazinilurea.
