Abstract: front page image
(EN)A process for preparing 3,4-disubstituted phenylacetic acids of the formula (I) in which X is fluorine, chlorine, bromine or iodine and R is C1-C4-alkylthio, C1-C4-alkylsulfonyl or C1-C4-alkylsulfoxide, starting from a 2-halo-C1-C4-alkylthiobenzene of the formula (II) in which X is as defined above and R1 is C1-C4-alkylthio.
(FR)La présente invention concerne un procédé de synthèse d'acides phénylacétiques 3,4-disubstitués de formule (I), dans laquelle X représente fluor, chlore, brome ou iode et R représente un groupement alkylthio en C1-C4, alkylsulfonyle en C1-C4 ou alkylsulfoxyde en C1-C4, en partant d'un 2-halogéno-(alkyle en C1-C4)thiobenzène de formule (II), X étant tel que défini ci-avant et R1 représentant un groupement alkylthio en C1-C4.
