A process for preparing 3-alkylsulfinylbenzoyl derivatives of the formula (IIIa) by reaction of 3-alkylsulfinylbenzoic acids of the formula (Ib) with compounds of the formula (II) in the presence of a chlorinating agent and a base is described. In the abovementioned formulae, Y is a radical such as pyrazolyl or cyclohexanedionyl. R 1 , R 2 and R 3 are radicals such as halogen, nitro, cyano and alkyl. |
