Title: PROCESS FOR THE MANUFACTURE OF CARBOXYLIC ACIDS OR CARBOXYLIC ACID DERIVATIVES
Abstract:
This invention concerns a process for the manufacture of carboxylic acids or carboxylic acid derivatives and a process for the manufacture of agrochemically and pharmaceutically active compounds comprising the process for the manufacture of carboxylic acids or their derivatives. The process for the manufacture of carboxylic acids or carboxylic acid derivatives comprises the steps of: a) halogenating a compound of formula (I): R1-C(O)-CHX2, to obtain a compound of formula (II): R1-C(O)-CX2X', b) transforming the compound of formula (II) in the presence of a compound A into a compound of formula (III): R1C(O)Z, wherein Z is a residue selected from the group consisting of -OH, -O-, -NR'R'. The process can optionally comprise additional steps.
