PROCESS FOR PREPARING 3-ALKYLSULFINYLBENZOYL DERIVATIVES.

摘要

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. R1, R2 and R3 are radicals such as halogen, nitro, cyano and alkyl.
