Abstract

La presente invención se refiere a un método para la preparación de 2-hidroxiarilaldehido, el cual comprende hacer reaccionar un halogenuro de ariloximagesio, derivado de un fenol que tiene al menos una posición en orto linbre en relación al grupo e hidroxi fenólico con formaldehído, o un compuesto de liberación de ormaldehido bajo condiciones substancialmente anhidras en la presencia de un disolvente orgánico polar diferente a la hexametilfosforamida o de la 1,3-dimetil-3,4,5,6-(1HO-pirimidona.The present invention relates to a method for the preparation of 2-hydroxyaryl aldehyde, which comprises reacting an aryloxyage halide, derived from a phenol having at least one position in ortho linkage relative to the group and phenolic hydroxy with formaldehyde, or an ormaldehyde-releasing compound under substantially anhydrous conditions in the presence of a polar organic solvent other than hexamethylphosphoramide or 1,3-dimethyl-3,4,5,6- (1HO-pyrimidone.
