Abstract

Si descrive un procedimento migliorato per la preparazione di 2-allil fenoli carbossilati di formula generale (I) (FORMULA I) che consiste in una prima fase di contemporanea esterificazione ed eterificazione di un fenolo carbossilato, il successivo riarrangiamento del prodotto così ottenuto ad allil fenolo allil carbossilato, e nella saponificazione finale di quest'ultimo a 2-allil fenolo carbossilato.
