Abstract

έθοδος παρασκευής 2-αλκανυλο-4-αλογονο-5-ακυλαμινο-φαινολών, χαρακτηριζομένη έκ του ότι παράγωγον της 3-ακυλαμινο-4-αλογονοφαινόλης του γενικού τύπου(Ι) είς τον οποίον το R1 είναι αλκανυλομάς, το R2 ακυλομάς και το Χ ατομον, αλογόνον, θερμαίνεταιπαρουσία καταλύτου ώστε να λάβη χώραν ανακατάταξις FRIES και λαμβάνεται 2-αλκανυλο-4-αλογονο-5-ακυλαμινοφαινόλη, του γενικού τύπου (ΙΙ) είς τον οποίον τα R1,R2 και Χ παριστούν ότι προηγούμενως περιεγράφη. Process for the preparation of 2-alkanyl-4-halo-5-acylamino-phenols, characterized in that it is a derivative of 3-acylamino-4-halophenol of general formula (I) in which R1 is alkanyl, R2 acyl and X atom , halogen, is heated in the presence of a catalyst to give a FRIES reclassification to give 2-alkanyl-4-halo-5-acylaminophenol of general formula (II) wherein R1, R2 and X are as previously described.
